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.

Electronic symbol. In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone.

Knowing that the energy stored in a capacitor is UC = Q2 / (2C), we can now find the energy density uE stored in a vacuum between the plates of a charged parallel-plate capacitor. We just have to divide UC by the volume Ad of space between its plates and take into account that for a parallel-plate capacitor, we have E = σ / ϵ0 and C = ϵ0A / d.

Then it stops. Call this maximum voltage V. The average voltage across the capacitor whilst it''s being charged is (V/2), so the average power being delivered to it is I (V/2). It was charged for T seconds, so the energy stored in the capacitor is T I (V/2). The charge accumulated on the capacitor is Q = I T, so the total energy stored is Q (V/2).
