TECHNICAL PAPER

Tantalum and Tantalum Polymer capacitors are suitable for energy storage applications because they are very eficient 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.
