Abstract
The utility model discloses a novel stacked wound film capacitor, which comprises a metallized film used for manufacturing a film capacitor via a winding method. The metallized film comprises a conductive metal layer and an insulating dielectric layer, and the conductive metal layer is coated on the insulating dielectric layer. The metallized film is provided with a longitudinal slit which is uncovered with the metal layer and has certain width, and a margin of the metallized film is formed by the longitudinal slit. The metallized film is further provided with a plurality of transverse narrow slits uncovered with the metal layer to completely separate adjacent metal layer units. A stacked effect can be achieved after the metallized film is wound to be processed into a capacitor, and then the capacitor has the advantages of low consumption and high charge-discharge resistant capacity as a stacked capacitor and simultaneously overcomes shortages of poor self-healing capacity of the stacked capacitor, thereby achieving optimization of performance of the capacitor.
