ABSTRACT:
A capacitor has a capacitor element including a metallized film and a case for hermetically containing the capacitor element. The capacitor element has a protective mechanism for protecting it against insulation breakdown at overvoltage or thermorunaway. The capacitor also has a safety device for keeping the capacitor safe at high internal pressure due to heating. Thus, the protective mechanism and the safety device operate surely, the capacitor is protected under various severe conditions, and the life of the capacitor becomes longer.
