A capacitor''s ripple current rating indicates the maximum AC current that should be allowed to pass through the capacitor. Because current flow through a capacitor results in self-heating due to ohmic and dielectric losses, the amount of current flow a given device can tolerate is finite, and is influenced by environmental conditions.
