> Has anyone known figures for leakage currents for larger > sized supercaps and for Nichicon Evercaps in particular. I don't have exact figures but when I used a 1F/5.5V capacitor I was also surprised by the similar leakage figures in the datasheet. In practice, this cap held 3V after spending 6 months in the drawer. My only explanation is that the leakage figures are for maximum voltage and temperature and fall dramatically with lover voltage.
