A CR2032 battery is a non-rechargeable (primary) lithium coin or “button” cell battery that is 20mm diameter x 3.2mm thickness.CatalogWhat is Coin Cell Battery?Overview: CR2032 vs bR2032CAD Model: CR2032 vs BR2032Specifications: CR2032 vs BR2032Features & Benefits: BR2032  CR2032Pinout: CR2032 vs BR2032Application: CR2032 vs BR2032Application CircuitsBattery Chemistry: CR2032 vs BR2032FAQWhat is Coin Cell Battery?Coin cell batteries are the “larger” varieties of the button cell battery family. They are still small, usually no bigger than 25mm in diameter. Compared to their smallest button cell battery cousins, at 5mm, they are quite larger.Coin cell batteries are single cell, typically disposable (but not always, as we’ll see), and measured in millimeters due to their small size. Their charge capacity is given in milliampere hours (mAh).Coin cells have a long service life, from one to 10 years, depending on the type. They have a low self-discharge rate and hold charge for long periods of time when not in use.  Overview: CR2032 vs bR2032CR2032 battery is the most common '2032' battery and its standard label is, of course, CR2032, but various manufacturers also use other labels as well, including CR2032BP, DL2032, ECR2032, KCR2032, BR2032, LM2032, 5004LC, 5004LB, L14, SB-T15, EA2032C, EA-2032C, L2032, DJ2032, KL2032, E- CR2032, KECR2032, GPCR2032, KT-CR2032, etc. BR2032 battery is another non-rechargeable 3V lithium battery featuring Carbon monofluoride as the positive electrode (cathode), organic electrolyte, and lithium as the negative electrode (anode).BR2032 are not as common as CR2032 and the manufacturers that do make them, label them simply 'BR2032'. CAD Model: CR2032 vs BR2032 symbol BR2032 vs CR2032  Footprint BR2032 vs CR2032  Specifications: CR2032 vs BR2032Product AttributeAttribute Value BR2032  Attribute Value CR2032Manufacturer:PanasonicMurataProduct Category:Coin Cell BatteryCoin Cell BatteryShipping Restrictions:Available in USA only.Available in USA only.RoHS:Not ApplicableNot ApplicableSeries:BRCRBattery Size:BR2032CR2032Battery Chemistry:Lithium Carbon Monofluoride (LiCF)Lithium UnspecifiedOutput Voltage:3 V3 VCapacity:200 mAh220 mAhRechargeable/Non-Rechargeable:Non-RechargeableNon-RechargeableTermination Style:Pressure ContactsPressure ContactsWidth:20 mm20 mmHeight:3.2 mm3.2 mmMinimum Operating Temperature:- 30 C- 30 CMaximum Operating Temperature:+ 80 C+ 70 CPackaging:TrayTrayBrand:Panasonic BatteryMurata ElectronicsProduct Type:Coin Cell BatteryCoin Cell BatteryFactory Pack Quantity:2025Subcategory:BatteryBatteryPart # Aliases:BR-2032/BN97384018 97384019 97384216 97384021 97384022 97384205 97384023 97384024 97384642 97384643 97384644 97384645 97384647 97384648 97384649 97384646Unit Weight:0.088185 oz0.112877 oz  Features & Benefits: BR2032  CR2032BR2032  CR2032 High voltage of 3 voltsGood pulse capability Extremely small self-discharge forHigh discharge characteristicslong service and shelf lifeStable voltage level during dischargeCompact and lightweight with extremelyLong-term reliabilityhigh energy density per unit weightCoin Cell Battery Chemistry Strong load pulse characteristics   Pinout: CR2032 vs BR2032CR2032 and BR2032 own the similar Pinout 2032 Battery Pinout Application: CR2032 vs BR2032CR2032 and BR2032 own the similar Applicationscomputer memory backupGames and toyssmall medical equipment such as home and portable blood pressure monitorswearable medical monitors such as the Dexcom system for monitoring glucose levels . Key fob for cars.Wireless doorbell for house.CMOS battery in computers.GlucometersDigital thermometersDigital altimeterCyclocomputers Application Circuits CR2032 Battery example in led circuit There are many applications of coin cell batteries, the below circuit shows you how to connect a CR2032 coin cell battery with a simple LED circuit. CR2032 provides a nominal voltage of 3.0V, to power up a simple LED we need a minimum voltage of 2.2V so we have used the resistance for protection or current limiting. led circuit  BR2032 Battery example in hotel circuit hotel circuit Battery Chemistry: CR2032 vs BR2032A battery’s chemistry can have great effects on its performance. Here are other things that can be affected by what a battery is made of:Performance at various temperaturesRechargeability vs. disposableGravimetric energy density -- how much energy a battery holds vs. its weightService life - while in useShelf life - when not in useThe two coin cell batteries we’ll be examining each have their own chemical make-ups for their positive cathodes. Let’s look at them now. CR2032 Battery ChemistryThe “CR” in a CR2032 battery or any CR-designated battery designates that its positive cathode is made of  Lithium manganese dioxide. This gives it a high energy density while also allowing it to function in low-temperature environments. BR2032 Battery ChemistryA battery with a BR denotation is made from Lithium carbon monofluoride. This gives them an incredible shelf life, up to 7 years. Like the CR batteries, they carry a 3V charge.Note that all three types of 2032 batteries are some form of lithium battery, as lithium is combined with other chemicals in their makeup. This does mean that every lithium battery is created equal.For example, you can safely replace most CR2032 coin cell batteries with a BR2032 type lithium battery. You can not, however, always substitute a LiR2032 rechargeable battery for either a CR2032 or BR2032 type, without running safety risks, including overheating and fire. Datasheet: CR2032 vs BR2032CR2032 DatasheetBR2032 Datasheet FAQCan CR2032 replace BR2032?It is not recommended to use the CR2032 instead of BR2032. BR2032 battery has better temperature range and less self-discharge so in the long run the BR2032 voltage would be better to use. Are CR2032 and BR2032 the same?However, there are two main models on the market today: the CR2032 batteries and the BR2032 ones. The main difference between these two types resides in their electrode. While similar, the BR2032 uses carbon monofluoride as the positive electrode. The CR2032 uses manganese dioxide for the positive electrode. What battery can replace CR2032?CR2025 batteryThe CR2025 battery is an extremely common lithium coin cell battery and is used in similar amounts and in similar applications as the CR2032. The CR2025 is slightly better suited for use in products that have less available mounting space than those that would use a CR2032. What are the “larger” varieties of the button cell battery family?Coin cell batteries How long does a coin cell battery life last?one to 10 years What is the most common 2032 battery?CR2032 What is the nominal voltage of a CR2032 coin cell battery?3.0V What type of battery does a CR2032 battery consist of?Lithium What type of lithium battery can you replace most CR2032 coin cell batteries with?BR2032 What type of battery can you replace for a CR2032 or BR2032 type?LiR2032 rechargeable battery

2N3904 and 2N2222 are the two most popular NPN bipolar junction transistors in the electronics market. In addition, 2N3904 and 2N2222 are similar in appearance.Therefore, some people may have questions: Why is 2N3904 so popular and 2N2222 is not always used? If you are curious about which one to use, or which is better, which is better? In this blog, we will compare the chip characteristics and pin diagrams of these two transistors.Comparing transistors is not extensive, because only a few useful parameters are important. This is a comparison table of transistors, which explains the meaning of everything in the table.CatalogI Differences between 2N3904 VS 2N2222II 2N3904 NPN Transistor Basics2.1 Specifications of 2N2222 Motor Driver IC2.2 2N3904 NPN Transistor PinoutsIII 2N2222 NPN Transistor Basics3.1 Specifications of 2N2222 Motor Driver IC3.2 2N2222 NPN Transistor PinoutIV FAQI Differences between 2N3904 VS 2N2222 2N39042N2222Type of BJTNPNNPNType of TransistorBipolar Junction Transistor (BJT)Bipolar Junction Transistor (BJT)Maximum voltage that the collector of the transistor can handle(called the collector-emitter voltage, VCEO)200mA1AMaximum current that the transistor can handle from the emitter to the collector(called collector current, Ic)40V40VBoth the 2N3904 and 2N2222 are identical in terms of handling collector-to-emitter voltages, and both can handle voltages of up to 40V. In simple terms, this effectively means that 40V is the maximum amount of voltage that the transistor can handle minus the voltage drop across the load connected to the collector. For example, suppose we apply 70V to the collector of the transistor and the load will consume 20V, this means that the remaining voltage will fall on the transistor which will be 70V - 20V = 50V. this would not be acceptable because it exceeds the maximum VCEO. since the 2N3904 and 2N2222 have the same maximum VCEO voltage, there is no difference in this regard.Where they differ is that the 2N2222 can handle larger operating collector currents. Collector current is the amplified current that flows from the emitter to the collector to power the load that may be connected to the transistor. 2N3904 can handle up to 200mA (milliamperes) of current flowing from the emitter to the collector terminal. A 2N2222 can handle up to 5 times that amount of current, as it can handle up to 1A (amps) of current flow from emitter to collector to power a load.II 2N3904 NPN Transistor Basics2N3904 NPN TransistorThe 2N3904 is a common NPN bipolar junction transistor used for general purpose low power amplification or switching applications.
