Tantalum Capacitors

Tantalum capacitors, commonly referred to as "tantalum electrolytic capacitors," are a specialized type of capacitor that is commonly used in a variety of applications, ranging from audio devices to miniature electronic circuits. They are some of the most commonly used passive components due to their small size, low cost, and high efficiency. The specific type of capacitor being discussed here, 299D476X0025FB1E3, is typically used in applications where a high-frequency/low-leakage performance is required.

Application Field

The 299D476X0025FB1E3 tantalum capacitor is particularly suitable for high-frequency and small signal circuits in computer peripheral applications, as well as for assembled or miniaturized electronic equipment. Its relatively small size and high reliability make it a great choice for applications that require a low noise and precise signal transmission.

Additionally, the 299D476X0025FB1E3\'s high-frequency performance makes it an ideal choice for a variety of consumer electronics, including cellphones, tablets, and computers. Its small size allows these devices to be small and light, but still provide superior performance. Furthermore, the device is also becoming increasingly popular in medical applications due to its small size and high level of accuracy.

Working Principle

A tantalum capacitor, like all types of capacitors, is a device that stores electrical energy. Unlike a normal capacitor, however, the tantalum capacitor is made up of two layers of tantalum oxide, which is what gives it its high-frequency and leakage characteristics. When current flows into the device, it creates an electric field between the two layers of oxide, allowing electric charge to accumulate.

When the device is disconnected, the stored electric charge will slowly dissipate, and the voltage and capacity of the capacitor will decrease accordingly. This is the reason why this type of capacitor is typically used in applications that require a high-frequency/low-leakage performance, as the stored charge will quickly dissipate if it is disconnected A tantalum capacitor is typically rated to have a capacity of around 10-500uF, with its working voltage range being between 10-210 volts.

Conclusion

The 299D476X0025FB1E3 tantalum capacitor is a special type of capacitor that is commonly used in many high-frequency and small signal circuits. Its small size and high performance make it a great choice for a variety of electronic devices, ranging from computers to medical equipment. The device is composed of two layers of tantalum oxide, which produces an electric field when current is applied, allowing for the storage of electric charge. When disconnected, the stored charge will dissipate, which is why it is mainly used for high-frequency/low-leakage applications.
