ELECTRIC DOUBLE LAYERED CAPACITOR

摘要

PURPOSE:To prevent the capacitance of an electric double layered capacity from deteriorating by overvoltage pulses. CONSTITUTION:This capacitor is so arranged that overvoltage is not applied directly to an electric double layered capacitor 1 by connecting a varistor 2 or an arrestor 2 in parallel with the electrolytic capacitor 1. This prevents the capacitance deterioration or the drop of reliability of an electrolytic double layered from occurring by the overvoltage not less than the rated voltage mixed in as a noise from outside.
