What is a capacitor?Capacitor, a electronic component to hold charges, represented by the letter C. It composes of two metal electrodes between a layer of insulating dielectric. When a voltage is applied between the two metal electrodes, the charge is stored on the electrode, so the capacitor is an energy storage electrical part. Any of two conductors that are insulated and close to each other form a capacitor. In addition, the parallel plate capacitor consists of the electrode plate and the die ...
The solid-state capacitor is called a solid-state aluminum electrolytic capacitor. The biggest difference between it and ordinary capacitors (i.e. liquid aluminum electrolytic capacitors) lies in the use of different dielectric materials. The dielectric materials of liquid aluminum capacitors are electrolyte, while the dielectric materials of solid capacitors are electroconductive polymer materials.Electronic Basics #14: CapacitorsCatalogI.

In autumn, an abundance of fallen leaves from deciduous phoenix trees are scattered around the streets in Northern China. These leaves are generally burned in the colder season, exacerbating the country's air pollution problem.Investigators in Shandong, China, recently discovered a new method to convert this organic waste matter into a porous carbon material that can be used to produce high-tech electronics. The advance is reported in the Journal of Renewable and Sustaina ...
New Yorker Electronics has introduced a series ruggedised aluminium electrolytic capacitors with welded seals, the MLSG in both Flatpack and Slimpack. This series targets compact power supply applications in military and aerospace, as well as other critical systems.Design enhancements and an electrolyte push the MLSG to nearly double the operating life of its predecessor, the MLSH, at no added cost.Two principal package profiles are offered in this technology, the MLSG Flatpack which measures ju ...
TDK Corporation presents the LCap, a new film capacitor from EPCOS for motor applications. LCap combines an AC capacitor with a choke coil in a single case, cutting costs and halving assembly times. Savings also result from the fact that only two leads are now required instead of four as before. The choke coil is molded into the capacitor case, leading to further benefits such as reduced sensitivity to external influences as well as higher long-term stability compared to discrete solutions. LCap ...
Industrial design researchers at Brunel University London have solved two of the major challenges which prevent everyday items of clothing being turned into power sources for smartphones, tablets and other personal tech.Technology to produce super capacitor thread capable of being made into cloth has been around for some time. But until now scientists have been unable to make it provide sufficient voltage for most devices or devise a method to produce it economically outside the lab.Now patented ...

“What capacitor types should I choose?” This is a question asked by many beginners. I will give you a simple answer to this question without going into all the details. After reading this, my goal is that you should be able to go and find the capacitor you need right away. I realized that it would be helpful to explain why one might pick one capacitor type over another. This information is important because there are a lot of factors (temperature characteristics, package, etc.) that might m ...
IntroductionSMT is a surface mount technology, which is one of the most popular technologies and processes in the electronic assembly industry.It is a type of circuit assembly technology making pin-less or short-lead surface assembly component (SMC/SMD) mounted on the surface of a printed circuit board (PCB) or on the surface of other substrates, in other words, circuit assembly technology for welding and assembling by reflow soldering or immersion welding.Abbreviation:SMT Full Name:Surface ...
