Usage
Production of high capacity capacitors and current rectifiers. Such capacitors use tantalum pellets obtained by powder metallurgy, sintered and pressed at high temperatures. The active surface of the porous tantalum pellet increases a hundredfold, which makes it possible to obtain a high-capacity capacitor with small dimensions. Tantalum capacitors are also used in military radios, as they can operate under very extreme conditions at temperatures of -80 +200°C.
