Abstract
A capacitor having an enhanced dielectric breakdown strength is obtained m a base dielectric film by coating the base dielectric film on both sides with an adherent coated dielectric film having a dielectric constant that is at least 50 percent higher than that of the base dielectric film and that adheres to the base dielectric film; and wherein metal foil is adherently joined to each of the coated dielectrics films to form electrodes for the capacitor.
Claims11
A capacitor having an increased dielectric breakdown strength consisting of:
- a cleaned base dielectric film having at least two major surfaces and having a first dielectric constant;
- a solid coating on the base dielectric film, the coating covering the two major surfaces, thereby sandwiching the base dielectric film, and the coating having a second dielectric constant which is at least 50% greater than the first dielectric constant of the base dielectric film, wherein a breakdown voltage of a composite of the base dielectric film and the coating is greater than a sum of breakdown voltages for the coating and the base dielectric film taken individually, wherein each of the coatings has an outer surface;
- and
- metal foil adheredly bonded to each of said outer surface of the coatings to form electrodes for the capacitor.
