what chemical in capacitor leak
The lower leakage current, the better the capacitor. In good electrolytic capacitors this current does not exceed tens-hundreds micro-amps (de-pending on the size, temperature and applied voltage). The chemical composition of the electrolyte must ensure recovery of the aluminum oxide layer to micro-damage.he lower leakage current, the better the capacitor.
