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 ···
