Supercapacitors(EDLC) FAQ

Quality/Reliability

I would like to use supercapacitor with higher voltage than rated voltage. What should I do?

Please use several supercapacitors in series. When using capacitors in series, use balance resistance in parallel to capacitor or use an active balance circuit. For more details, see Murata's specification sheet.
If there are temperature gaps between capacitors, voltage will lose balance. Ensure that there is no temperature gap between capacitors.
For more details about voltage balance, please see "Recommended balance condition"
