Abstract
A metallization film capacitor that achieves both high heat resistance and high withstand voltage at the same time. A metal-deposited electrode is formed on a PEN film in each of a pair of metalized films. These metalized films are wound such that the metal-deposited electrodes face each other via the dielectric film in between. A metalized contact electrode is formed on both end faces of these wound metalized films to configure the metallization film capacitor. A divisional electrode is provided on the metal-deposited electrode. In addition, a fuse is coupled to this divisional electrode for providing a self-maintaining function. Pass rate a/b of a deposition pattern is set to 4.0 or smaller, where ‘a’ is the fuse width, and ‘b’ is the length of the divisional electrode in a lengthwise direction of the metalized films.
