Introduction to Capacitor Technologies
The dielectric materials used in capacitors are not ideal insulators. A small DC current can flow, or "leak" through the dielectric material for various reasons specific to each dielectric. As a result, when a capacitor is charged to a certain voltage, it will slowly lose its charge. As it loses its charge, the voltage between the capacitor''s electrodes will drop. The leakage current (LC ...
