High energy density capacitor films and capacitors made therefrom

摘要

Materials from which metal film capacitors with plastic or other dielectric films are formed include a plurality of regions or segments defining plates of a capacitor, the regions electrically interconnected by fuse regions which separate a region containing a short circuit fault from the capacitor. The plurality of regions or segments are circular. The fuse regions may be circular or may alternatively be high resistivity regions filling spaces between the plurality of regions or segments. A capacitor having a higher energy storage density and safer construction is wound from these materials using conventional techniques.
