Abstract
A film capacitor preferably includes a single film capacitor layer wound around itself in adjacent layers to form a winding. The film capacitor layer preferably includes a dielectric film, a first metallization layer formed on the dielectric film, a dielectric coating formed on the first metallization layer, and a second metallization layer formed on the dielectric coating. A metallic contact layer is preferably formed on an outer edge of the winding. A terminal is preferably formed on an outer edge of the metallic contact layer. An insulating material preferably encapsulates the winding, the metallic contact layer, and a portion of the terminal. The capacitor as self-healing properties. Further, the border of the electrodes may be wave-cut. Further, an insulating gap may be added between the border and the upper electrode.
