What Are Tantalum Capacitors?

The full name of tantalum capacitor is tantalum electrolytic capacitor, which is also a kind of electrolytic capacitor. The solid tantalum capacitor was first developed by Belle Laboratories in the United States in 1956. Tantalum capacitors use tantalum metal as the dielectric, do not need to use the electrolyte like ordinary electrolytic capacitors, and do not need to use aluminum-coated capacitor paper for firing.

Tantalum capacitor

1. Because there is no electrolyte inside, it is very suitable for working at high temperature 2. Long life, small size, stable function, high accuracy, excellent high frequency filtering and wave changing performance 3. Can work under extremely severe conditions 4 , Small capacity, more expensive than aluminum capacitors, withstand voltage and current capacity is relatively weak 5, the working voltage has a certain upper limit of the par value

Tantalum capacitors are not only widely used in military communications, aerospace and other fields, but the application range of tantalum capacitors is also widely used in industrial control, film and television equipment, communication instruments and other products. It also has the ability to store electricity, charge and discharge, and is used in filtering, energy storage and conversion, symbol bypass, coupling and decoupling, and as a time constant element.

In the application, pay attention to its performance characteristics. Proper use will help to fully perform its functions, such as taking into account the extreme working temperature of the product's working environment, and taking derating measures. Improper use will affect the product's working life.
