Tantalum Capacitors

Tantalum capacitors are processed from the rare metal tantalum, which is first ground into a micro-fine powder and then sintered together with other media. The current process has two kinds of dry powder molding method and wet powder molding method. Tantalum capacitors due to the intrinsic nature of the metal tantalum, has a good stability, does not change with the changes in the environment, can do a lot of capacitance and so on, in some aspects of ceramic capacitors can not be compared with some of the characteristics of tantalum capacitors, so in many can not use ceramic capacitors on the circuit tantalum capacitors are widely used.

At present the world's major tantalum capacitors of the following brands: AVX, KEMET, VISHAY, NEC, of which AVX and VISHAY's production is the largest, and the best quality.
