摘要： A metalized film capacitor capable of exhibiting stable performance in a wide temperature range is provided. The metalized film capacitor has an elliptical cross sectional shape having a major axis of 60 mm or above. In this capacitor, offset for shifting in the width direction of a pair of metalized film is set to 1.2 mm or above. Since the bonding state between metal vapor-deposited electrode and metal sprayed electrode formed on the end surface is stable, a stable contact between metal sprayed electrode and dielectric film is maintained, thereby preferably maintaining tan σand exhibiting excellent performance even if the use temperature range is increased and the thermal stress is increased.

摘要： 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.

摘要： A method of manufacturing a both-side metallized insulation film comprises steps of: depositing zinc or a blend of zinc and aluminum onto both sides of an insulation film; and winding this metallized film into a product roll. The method is characterized in spraying an oxidizing gas onto a deposited layer on an inner side of the insulation film to be wound, during the winding step. During a vacuum deposition step, an oil layer is formed on at least one side of the metallized film. In addition, an oxide layer is formed by exposing a deposited layer on at least one side to oxygen, or by spraying an oxygen-containing gas onto the deposited layer on at least one side during the winding of the metallized film into the product roll.

摘要： A metallized film capacitor is made by winding or laminating a both-side metallized polypropylene (PP) film and a non-metallized PP film. Limiting the heat shrinkage factor and the thickness of the PP films, the position of deposited electrodes, and the rate of the peeled area of the deposited electrodes to a certain range provides a metallized film capacitor having improved dieletric strength, tan δ, and charge-discharge characteristics.
