A tantalum electrolytic capacitor is an electrolytic capacitor, a passive component of electronic circuits. It consists of a pellet of porous tantalum metal as an anode, covered by an insulating oxide layer that forms the dielectric, surrounded by liquid or solid electrolyte as a cathode. Because of its very thin and relatively high permittivity dielectric layer, the tantalum capacitor distinguishes itself from other conventional and electrolytic capacitors in having high capacitance per volume (high volumetric efficiency) and lower weight.
The uses of these types of capacitors are:
- These are utilized in the circuits of ‘Sample and Hold’. …
- Because of the stability and the compact size, these are used in the supply circuits for filtering.
- It can be used in the ‘Military Specifications Versions (MIL-SPEC)’. …
- In the field of electronics which are used in Medical, these capacitors are preferred because of the stable behaviour.
