In today’s world, electronics are everywhere. From smartphones to medical devices, they power modern life. But these devices face a hidden challenge: electromagnetic interference (EMI). This interference can disrupt their performance or even cause them to fail. That’s where EMI/EMC filters come in. These filters ensure electronics work reliably by blocking unwanted signals.As technology advances, the need for these filters grows. For example, the EMI/EMC filters market is expected to nearly double, from $1.5 billion to $2.8 billion by 2032. The rise of 5G, with higher frequencies and faster data rates, brings more interference. Smaller devices also demand compact filters with high performance. Without these filters, modern electronics would struggle to keep up with the demands of 2025.Understanding EMI and EMCWhat is electromagnetic interference (EMI)?Electromagnetic interference, or EMI, occurs when unwanted electromagnetic signals disrupt the normal operation of electronic devices. These signals can come from various sources, such as power lines, motors, or even other electronic devices. For example, when you hear static on your radio while using a nearby hairdryer, that’s EMI in action.Recent studies indicate that the high-speed switching of SiC MOSFETs can lead to significant EMI issues due to the interaction with parasitic components in the circuit. The primary sources of EMI are linked to rapid changes in voltage and current (dv/dt and di/dt), which generate high-frequency noise. Additionally, the use of passive filters with high insertion loss is recommended to mitigate conducted EMI noise in motor drive control systems.EMI can be classified into two types: conducted and radiated. Conducted EMI travels through wires or cables, while radiated EMI spreads through the air. Both types can interfere with sensitive electronics, making EMI/EMC Filters essential for maintaining device performance.What is electromagnetic compatibility (EMC)?Electromagnetic compatibility, or EMC, ensures that electronic devices can operate without causing or experiencing interference. In simple terms, EMC means your devices can work together without disrupting each other. For instance, your smartphone and Wi-Fi router can function simultaneously without interference because they meet EMC standards.Achieving EMC involves designing devices that emit minimal electromagnetic noise and can resist external interference. However, this process can be challenging.ChallengeDescriptionHigh CostsSignificant expenses for SMEs in acquiring and maintaining EMC testing facilities.Complexity of TestingIncreased operational costs due to the intricate nature of EMC testing procedures.Shortage of Skilled ProfessionalsLack of qualified personnel leads to delays and inefficiencies in testing processes.Demand for ComplianceGrowing need for adherence to stringent EMC regulations in sectors like automotive and telecommunications.How EMI and EMC impact electronic devicesEMI and EMC directly affect the reliability and functionality of electronic devices. EMI can cause malfunctions, data loss, or even permanent damage to sensitive components. For example, in medical equipment, EMI could disrupt life-saving devices like pacemakers.On the other hand, poor EMC design can lead to devices interfering with each other. Imagine a scenario where your car’s navigation system stops working because of interference from its entertainment system. This is why EMI/EMC Filters play a critical role in ensuring devices perform reliably, especially in today’s interconnected world.What Are EMI/EMC Filters?Definition and purpose of EMI/EMC filtersEMI/EMC filters are specialized components designed to manage electromagnetic interference and ensure electromagnetic compatibility in electronic devices. These filters act as barriers, preventing unwanted signals from disrupting the operation of your devices. They also help manufacturers meet EMC standards, which are essential for certifying products as safe and reliable.Without these filters, devices could emit excessive electromagnetic noise or fail to withstand external interference. For example, a poorly designed electronic device might interfere with nearby equipment, causing malfunctions. EMI/EMC filters ensure that your devices operate effectively within their electromagnetic environment, making them indispensable in modern electronics.Tip: If you're designing or using electronic devices, always check for EMC compliance. It ensures your devices won't disrupt others or be disrupted themselves.How EMI/EMC filters suppress interferenceEMI/EMC filters suppress interference by controlling the frequency components of signals within electronic circuits. They block unwanted noise while allowing desired signals to pass through. This process enhances the performance of your devices and ensures they function reliably.Here are some common configurations used in EMI/EMC filters:Feed-through capacitors: The simplest form, ideal for basic noise suppression.L-circuit filters: Combine inductors and capacitors for effective filtering.PI-circuit filters: Divert noise at high-impedance nodes.T-circuit filters: Suppress noise at low-impedance nodes.Filter TypeFunctionalityLow-Pass FiltersStop high-frequency noise from entering or leaving a system.Feed-Through CapacitorSimplest form of EMI filter, consisting of a single component.L-Circuit FilterA basic configuration that uses inductors and capacitors to filter noise.PI-Circuit FilterCombines capacitors and inductors to create a low-impedance path for noise at high-Z nodes.T-Circuit FilterDesigned for low-Z nodes, using inductors to suppress noise effectively.By placing these filters between circuits, you can effectively suppress conducted and radiated interference. This suppression minimizes disruptions and ensures your devices perform as intended.The role of EMI/EMC filters in ensuring device reliabilityEMI/EMC filters play a critical role in protecting sensitive electronics from electromagnetic interference. High levels of electrical noise can cause data loss, malfunctions, or even complete device failure. These filters act as shields, limiting the penetration of noise signals and safeguarding your devices.For instance, in medical equipment, EMI filters prevent interference that could disrupt life-saving devices like pacemakers. In industrial machinery, they ensure smooth operation by blocking noise from motors and power lines. The global EMI filters market, valued at $274.5 million in 2022, highlights their importance. With a projected growth rate of 4.1% annually, the market is expected to reach $392.1 million by 2031.Note: Investing in high-quality EMI/EMC filters not only boosts device reliability but also reduces maintenance costs and downtime.Key Components of EMI/EMC FiltersCapacitors: Their role in filtering high-frequency noiseCapacitors are essential in EMI/EMC Filters because they filter out high-frequency noise from electronic circuits. They work by creating a low-impedance path for unwanted signals, diverting them away from sensitive components. You’ll often find capacitors in power lines, where they decouple common-mode noise generated by switching power supplies (SMPS).Different types of capacitors serve specific purposes:X-capacitors: These inhibit differential mode interference, which occurs between two conductors.Y-capacitors: These filter common-mode noise, which flows between a conductor and ground.Decoupling capacitors also stabilize voltage levels by acting as local energy reservoirs. They provide current during transient conditions, ensuring a steady DC supply. This minimizes crosstalk in digital circuits, keeping your devices running smoothly.Inductors: How they block unwanted signalsInductors are another critical component in EMI/EMC Filters. They block unwanted signals by resisting changes in current. When high-frequency noise tries to pass through, the inductor creates a magnetic field that opposes the current flow, effectively filtering out the interference.The effectiveness of an inductor is often measured by its insertion loss. This parameter shows how much noise the inductor removes from the circuit. Engineers also use S-parameter measurements, like the transmission coefficient (S21), to evaluate how well the inductor blocks unwanted signals. These measurements ensure the filter performs as expected in real-world conditions.Resistors: Their contribution to damping and stabilityResistors play a supporting role in EMI/EMC Filters by providing damping and stability. They help control the oscillations that can occur when capacitors and inductors interact. By dissipating excess energy as heat, resistors prevent voltage spikes and ensure the filter operates reliably.In addition, resistors improve the overall performance of the filter by reducing the risk of resonance. This makes them indispensable in maintaining the stability of electronic circuits, especially in high-frequency applications.Tip: When designing EMI/EMC Filters, consider the specific noise profile of your application. This helps you choose the right combination of capacitors, inductors, and resistors for optimal performance.Ferrite beads: Reducing high-frequency noise in circuits.Ferrite beads are small but powerful components that help reduce high-frequency noise in electronic circuits. You’ll often find them in EMI/EMC Filters, where they act as barriers to unwanted signals. These beads are made from ferrite, a magnetic material that absorbs and dissipates high-frequency noise as heat.When you place a ferrite bead on a wire or cable, it creates a choke point for electromagnetic interference. High-frequency noise encounters resistance, while low-frequency signals pass through unaffected. This makes ferrite beads ideal for suppressing noise in power lines, USB cables, and audio circuits.Ferrite beads come in various shapes and sizes, each designed for specific applications. For example, cylindrical beads are common in power cords, while clip-on beads are used for retrofitting existing cables. Choosing the right ferrite bead depends on the frequency range and noise level of your circuit.Tip: When selecting ferrite beads, check their impedance at the target frequency. Higher impedance means better noise suppression.Varistors: Protecting against voltage spikes.Varistors are essential for protecting electronic devices from voltage spikes. These components act like electrical safety valves, absorbing excess energy during sudden surges. You’ll often see them in EMI/EMC Filters, where they safeguard sensitive circuits from damage.Varistors exhibit sharp voltage breakdown characteristics, similar to back-to-back Zener diodes. Multilayer varistors (MLVs) are particularly effective because they can withstand thousands of strikes at full rated peak current without degrading. Their response time is less than one nanosecond, making them ideal for fast voltage spike protection.Modern MLVs also feature reduced self-inductance, which minimizes voltage overshoot during spikes. This improvement ensures reliable performance in high-speed circuits. You’ll find varistors in applications ranging from consumer electronics to industrial machinery, where they protect against sudden power fluctuations.Key advantages of varistors:Symmetrical voltage breakdown for consistent protection.High durability under repeated surges.Ultra-fast response time for immediate action.Reduced self-inductance for better performance.Note: Always choose varistors with a voltage rating slightly higher than your circuit’s operating voltage. This ensures optimal protection without interfering with normal operation.How EMI/EMC Filters WorkThe basic working principle of EMI/EMC filtersEMI/EMC filters work by suppressing electromagnetic noise in electronic circuits. They allow desirable currents to flow while diverting unwanted currents to the ground. These filters are typically low-pass filters, meaning they let lower frequencies pass through while blocking higher frequencies that cause interference. This ensures that your devices operate without disruptions from external noise.To achieve this, EMI/EMC filters use passive components like capacitors and inductors. Capacitors create a low-impedance path for high-frequency noise, directing it away from sensitive components. Inductors, on the other hand, resist changes in current, blocking high-frequency signals. Together, these components form LC circuits that filter out harmful noise while allowing the desired signals to pass.Key principles of EMI/EMC filters:Suppress electromagnetic noise through conduction.Divert unwanted currents to the ground or back to the source.Allow AC line frequencies to pass while blocking harmful high frequencies.For example, in DC motors, EMI filters act as bypass components. They allow DC current to flow without affecting the motor's performance. At the same time, they reduce internal EMI through field cancellation, ensuring smooth operation.How filters suppress conducted and radiated interferenceEMI/EMC filters are designed to tackle two types of interference: conducted and radiated. Conducted interference travels through wires or cables, while radiated interference spreads through the air. These filters suppress both types by using a combination of capacitors, inductors, and other components.Conducted interference is often addressed by placing capacitors between power lines and the ground. For instance, Y-capacitors are highly effective in reducing common-mode noise, which flows between a conductor and the ground. Inductors are also used to block high-frequency noise in power lines, ensuring that only the desired signals reach your devices.Radiated interference, on the other hand, is suppressed by creating barriers that absorb or redirect electromagnetic waves. Ferrite beads, for example, are commonly used to reduce high-frequency noise in cables. They create a choke point for interference, allowing low-frequency signals to pass through while blocking unwanted noise.Frequency (MHz)Capacitor Value (pF)Inductor Value (nH)Insertion Loss Requirement30> 86< 327< 1167> 30< 30< 1At 30 MHz, a 470pF Y-capacitor shows lower impedance, enhancing EMI suppression. At 167 MHz, a 100pF Y-capacitor demonstrates superior performance. These components effectively reduce both conducted and radiated EMI across various frequency bands, ensuring reliable device operation.The importance of proper placement and designThe placement and design of EMI/EMC filters play a crucial role in their effectiveness. Improper placement can lead to reduced performance or even failure to suppress interference. To optimize filter performance, you need to understand the type of interference and the frequency behavior of your circuit.For example, placing filters close to the source of interference minimizes the distance that noise can travel. This reduces the risk of interference affecting other components. Additionally, designing filters with the right combination of capacitors, inductors, and resistors ensures that they target the specific frequency range of the noise.Simulation tools can also help you optimize filter design. By accounting for parasitic elements, these tools allow you to predict how the filter will perform in real-world conditions. This approach not only improves performance but also reduces development time and costs.Tips for effective filter placement and design:Place filters close to the source of interference.Use simulation tools to optimize performance.Choose components based on the specific noise profile of your application.Proper placement and design ensure that EMI/EMC filters meet product certification standards. They also enhance device reliability, making them an essential part of modern electronics.Practical Applications of EMI/EMC FiltersImage Source: unsplashEMI/EMC filters in consumer electronics (e.g., smartphones, laptops)You rely on consumer electronics like smartphones and laptops every day.

Do you want a photo book incorportating the sound of the sea and  birdsong,a novel with spoken dialog? Most Children may say yes.But how to invent such a product out? Yeah,this is all made possible by loudspeaker paper and electronic concealed in the cover. Such a T-book can currently be heard at the Frankfurt Book Fair ( here the T stands for the German word Ton,means sound ). Most fairs even book fairs are already loud enough. However,the future noise level looks like to keep increasing if the development on the display at the CPI booth of the Frankfurt(hall 4.0, booth F73) is successful. Not only in the halls of trade fairs, but also in living rooms, public transport and – God forbid – supermarkets, drugstores, and the like could all be equally affected.  Tchnicians at TU Chemnitz have now introduced the latest generation of their “T-books”after years of research and experimentation. The “T” here has nothing to do with Telecom, but stands for Ton (sound). In other words, the pages of the book are simultaneously loudspeakers and can therefore emit sounds of any kind. Sensors detect which pages are open, and the necessary audio electronics and SD card are concealed in the book’s cover. Naturally, given their frequency response the sound quality has no chance even compared to a kitchen radio. The bass is much too “thin”, but high and medium frequencies are quite well reproduced. And surprisingly loud. The Reason about Mass-producible paper loudspeakers Actually the technology behind it is relatively simple.Perfectly ordinary paper is printed with two layers of a conductive organi polymer that act as electrondes.Next,the active element is between them,a piezoelectric layer that causes the paper to vibrate, thus exciting the air and producing the sound. The remaining difficulty is primarily that of developing a cost-effective mass production for it. There is a true news that two years ago, the Chemnitz researchers implemented the World Press Photo Foundation's Yearbook as a T-book under the cooperation with the Munich Advertising Agency Serviceplan. Unfortunately,this audio-tome,which was mainly down to the battery is too heavy while it weighted more than 3kg.Unsurprisingly, this small-series product ultimately proved too unwieldy and too expensive.  That is why the original method of producing individual sheets is to be superseded by a roll process, which will optimize both performance and appearance of paper loudspeakers.  In future, the electronic components will also be printed. This will considerably increase the efficiency of the entire manufacturing process and open up mass markets such as photobooks. In future, for example, instruction leaflets could read themselves aloud, and books could become accessible to blind people. The opposite effect is also possible – loudspeaker paper could be used to construct a force sensor or a microphone. What is called the “direct piezoelectric effect” responds to an elastically deformed solid by producing a voltage. This means that there are any number of useful applications, not necessarily things like chatty packaging, singing wallpaper and similar strident marketing hype. 

Carbon-based memory materials promise to revolutionise how data is stored and to take computing to a new age in terms of speed, efficiency and power. Improved data storage represents the backbone of the knowledge economy, as well as modern industry, business and multimedia. Creating non-volatile data storage can be accomplished through new carbon-based memory materials, which was the aim of the Carbon resistive random access memory materials project.The project team investigated how to develop eco-friendly, cost-effective and energy-efficient memory materials that are scalable to the molecular level and boast a sub-nanosecond switching time with advanced functionality overall.To achieve its aims the team worked on two areas. On one hand it investigated amorphous-carbon based materials and devices in order to supplement current memory technologies such as hard disks and flash memory.On the other it considered graphene-oxide memories for possible use in flexible electronics applications. Storage capabilities in both concepts involved electrical resistive switching, which led to more in-depth research on the topic and establishment of the technology’s limitations, including minimum device size, temperature range and switching speed.The work involved experiments to pinpoint predicted lifetime at different temperatures, multi-level storage capability, suitability within specific applications, and several other pivotal parameters required to develop the technology. After intensive laboratory work, the team successfully built and characterised prototype devices that achieved almost all of the desired objectives.CARERAMM built nanometre amorphous-carbon based devices with sub-petajoule switching energy and oversaw their successful operation at temperatures reaching 300 degrees C. The project built graphene oxide-based devices with 4-level storage and endurance on flexible substrates, as well as GO-based devices that can resist more than 10,000 bending cycles and high bending radii.Overall the team has produced valuable knowledge on the cutting-edge of resistive switching concerning both amorphous carbon and graphene oxide based materials and devices. It combined atomistic scale modelling with nanoscale characterisation to improve switching considerably, paving the way for the commercialisation of advanced carbon-based memory in the near future.Reference:SDUS5EB-001GCXA1512M MT9VDDT6472HY-335 F2 

In electronics, lower power consumption leads to operation cost savings, environmental benefits and the convenience advantages from longer running devices. While progress in energy efficiencies has been reported with alternative materials such as SiC and GaN, energy-savings in the standard inexpensive and widely used silicon devices are still keenly sought. K Tsutsui at Tokyo Institute of Technology and colleagues in Japan have now shown that by scaling down size parameters in all three dimensions their device they can achieve significant energy savings.Tsutsui and colleagues studied silicon insulated gate bipolar transistors (IGBTs), a fast-operating switch that features in a number of every day appliances. While the efficiency of IGBTs is good, reducing the ON resistance, or the voltage from collector to emitter required for saturation (Vce(sat)), could help increase the energy efficiency of these devices further.Previous investigations have highlighted that increases in the "injection enhancement (IE) effect", which give rise to more charge carriers, leads to a reduction in Vce(sat). Although this has been achieved by reducing the mesa width in the device structure, the mesa resistance was thereby increased as well. Reducing the mesa height could help counter the increased resistance but is prone to impeding the (IE) effect. Instead the researchers reduced the mesa width, gate length, and the oxide thickness in the MOSFET to increase the IE effect and so reduce Vce(sat) from 1.70 to 1.26 V. With these alterations the researchers also used a reduced gate voltage, which has advantages for CMOS integration.They conclude, "It was experimentally confirmed for the first time that significant Vce(sat) reduction can be achieved by scaling the IGBT both in the lateral and vertical dimensions with a decrease in the gate voltage."Reference:2SA1987C4706KSC5024RTU  

Induction cooking appliances commonly make use of resonant topologies which allow bidirectional current flow. Additionally they demand a discrete IGBT that performs best at switching frequencies from 18 to 40kHz and has low losses. Infineon has launched a family of discrete IGBTs to address these needs. The RC-E devices are cost optimised and specifically meet the demands of low- to mid-price range induction cookers and induction rice cookers.Monolithically integrated reverse conduction diodeThe RC-E family features an IGBT with monolithically integrated reverse conduction diode for resonant switching. The technology used in RC-E IGBTs is also optimised for low switching and conduction losses. Lower losses allow designers to achieve efficiency and power targets for induction cooking applications more easily. Thus, less energy is consumed for cooking, leading to lower operating costs for consumers. With low E off, V F, R th and V ce(sat) this device sets a new industry benchmark in price/performance and ease-of-use.The new devices offer Infineon’s proven quality in discrete RC IGBTs and fulfill all the requirements for soft switching applications and efficiency as well as EMI standards. The RC-E delivers the well-established high-performance of its predecessors with a more attractive price for lower BoM cost. The RC-E is offered in a standard TO-247 package allowing a drop-in replacement for existing designs.Samples are available now and the devices are in production. The family will be launched with two devices: 15 A and 25 A, both with the most commonly used blocking voltage of 1200V.Reference:KY56-MN3306KY0-SE40PJ-M3/86A

When designing a custom lighting solution, there are many different goals to take into consideration. One of the most essential may be reducing the power supply needs of the system. Doing so can provide further benefits, such as improving reliability and expected shelf life, and reducing space and size constraints. Benefits often come with tradeoffs; traditionally, when you reduce power you may need to reduce brightness at the same time. The good news is that this doesn’t always have to be the case. GLOBAL LIGHTING TECHNOLOGIES have compiled a list of five smart ways that you can reduce power without sacrificing LED brightness. 1. LED efficiencyHow do you do more with less? It's all about efficiency, and choosing more efficient LEDs can make a world of difference. Choosing a more efficient LED may seem like a more expensive option, but keep in mind that it’s not just about the cost of the LED - what you should really be considering is the cost per Lumen of output. A more efficient LED is actually more cost-effective, while simultaneously helping reduce power needs. 2. Lightguide material efficiencyAny light which is absorbed by the lightguide material is light that the actual display is losing. Therefore, switching to a material with a higher transmissivity to improve efficiency and it will aid in the retention of more light. 3. LED driver circuitBy utilising a highly efficient LED driver circuit, you can prevent power loss and improve the end result. This is often overlooked, as many engineers design circuits which use resistors to reduce voltage and match current to the LEDs. You can prevent those power losses from occurring by using custom designed LED driver chips and circuits with improved efficiency. 4. Lightguide extraction efficiencyAnother area where efficiency can be improved is with extraction, and by doing so more light is able to reach the user’s target area. In turn, power can also be reduced. Our innovative extraction technology offers higher efficiency and overall improved extraction, helping to achieve this goal. 5. LightguidesThe job of a lightguide is to take the light from the LED and spread it out uniformly over the surface being illuminated. With the right design and technology, a custom lightguide can actually conserve most of the initial LED efficiency while greatly increasing uniformity of the display, offering the best of both worlds. Ref.KY32-HV9921N3KY32-MIC2287CBD5KY32-LNK456DG
