Tantalum Capacitor Introduction (I)

Advantages and disadvantages of tantalum capacitors.

Advantages.

Tantalum capacitors are called tantalum electrolytic capacitors, and they are also electrolytic capacitors. They use metal tantalum as a medium, do not use electrolytic solutions like ordinary electrolytic capacitors, and tantalum capacitor do not need to be fired with aluminum coated capacitor paper like ordinary electrolytic capacitors. There is little inductance in itself, but it also limits its capacity. In addition, because tantalum capacitors do not have electrolyte inside, it is suitable to work at high temperature. Tantalum capacitors are characterized by long life, high temperature resistance, high accuracy and excellent performance of filtering high frequency harmonics. . This unique self-healing performance ensures its long life and reliability advantages. Tantalum electrolytic capacitors have a very high working electric field strength and are larger than the same type of capacitors in order to ensure its miniaturization.

Shortcomings.

Smaller capacity, more expensive than aluminum capacitors, and weak resistance to voltage and current.
