ABSTRACT:
A metallized-film capacitor includes a slit (5a) at approx. center of the width (W) of an effective electrode which actually forms a capacitance of a pair of deposited electrodes (110, 210). Divisional electrodes (2a, 2b) exist at a place between the center and insulation margins (4a, 4b), and the electrodes (2a, 2b) are coupled in parallel to each other by fuses (7a, 7b) disposed away from metallized contacts (6a, 6b). Such a structure as placing fuses (7a, 7b) away from the contacts (6a, 6b) allows reducing a current supplied from the contacts (6a, 6b) and running through fuses (7a, 7b), thereby lowering heat generated from fuses (7a, 7b). As a result, a temperature rise in the metallized-film capacitor can be suppressed.
