Tantalum and Tantalum Polymer capacitors are suitable for energy storage applications because they are very efficient in achieving high CV. For example, for case sizes ranging from EIA 1206 (3.2mm x 1.6mm) to an EIA 2924 (7.3mm x 6.1mm), it is quite easy to achieve capacitance ratings from 100μF to 2.2mF, respectively.

What is a Capacitor Bank?

A capacitor bank is a physical group of several capacitors that are of the common specifications are connected in series or parallel with each other to form a capacitor bank that store electrical energy.
