Things you have to know about Ultra Capacitor

  [Introduction] Nowadays, with numerous kinds of enegy storage options, it has been a main stream to use ultra capacitors along( farad capacitor ) with the characteristics of high power, large current, wide working temperature ranges, high safety, and long cycle life, or in co···

Robustness of terminations

The capacitors ,inculding farad capacitor ,shall be subjected to Test Ua1, Ub,Uc and Ud of IEC 60068-2-21, as applicable. 1.Test Ua1—Tensile The force applied shall be: –for terminations other than wire terminations: 20 N; — for wire terminations, see Table 4. 2.Te···

Electric double layer capacitors : Self-discharge

This part of IEC 62391 applies to fixed electric double layer capacitors (called” supercapacitors”) mainly used in DC circuits of electronic equipment. Measuring method(refer to figure: Self-discharge test diagram) Before this measurement is made, the supercapacitor shall be f···

How to measure leakage current of supercaps

    In generally,  leakage current  is current that flows in supercaps that is thought to be in a “off” mode where ideally no current would flow. For  internation standard:IEC 62391-1,Leakeage current is a value of current that folws through a supercaps after a charge for a ···
