| Zusammenfassung: | The utility model relates to metallized film capacitors and aims at providing a metallized film capacitor. The metallized film capacitor comprises one or a plurality of capacitor elements, a casing used for holding the upper end face of the capacitor, provided with an opening portion and a bottom and in a cylindrical shape, a sealing piece for sealing the opening portion of the casing and filling resin for filling the casing. The sealing piece is fixedly arranged inside a structure of the casing at the opening end portion of the casing. Even if a gap is arranged at the joint portion of the sealing piece and the casing, the filling resin can not flow out of the casing from the gap portion during the process of injecting the filling resin. The metallized film capacitor is characterized in that an extending portion integrally extending from the periphery portion of the sealing piece is arranged on the side direction of the casing. The extending portion extends to the front end close to the inner side of the open |
