Customer Feedback :
Q: Why is the voltage of Supercapacitors so low?
A: In order for large capacitance, the dielectrics should be made very thin and thus the voltage will be low.
Q: How does the leakage current affect the super capacitor?
A: When the super capacitor’s voltage becomes stable, the voltage on each unit of the super capacitor will change as the leakage current (instead of capacitance) changes. The greater the leakage current, the lower the rated voltage and vice verse. This is because leakage current will cause the super capacitor unit to discharge and thus reduce its voltage. As a result, the voltage of other units connected in series with it will also be affected (assume that all the super capacitor units are powered by the same constant voltage).
