If pulse capacitors are to be used in applications where they are subject to permanent volt-age, this must be taken into consideration in capacitor design. The DC capacitance is the decisive factor for the energy yield. This characteristic is approximately 1.2 times the AC capacitance.
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.
Capacitor specifications of capacitance, DC leakage current (DCL), equivalent series resistance (ESR), size, etc. are typically room temperature measurements under a very specific test condition. Furthermore, energy storage capacitors will often be set up in some parallel/series combination that can pose unique challenges or unexpected behaviour.
Generally, the design of pulse capacitors can be optimized to customer demands. There-fore, actual values can differ greatly from the typical values listed above. Depending on customer requirements, capacitor designs with improved individual values are available on request.
