Abstract
This invention relates to capacitor films that have increased moisture and breakdown resistance. The capacitor films include a polymer coating that helps prevent air entrapment.
Claims39
A metallized film comprising:
- a dielectric film;
- a metal layer deposited on a portion of a surface of the dielectric film, wherein the surface of the dielectric film upon which the metal layer is deposited has a margin portion which is free of deposited metal;
- and
- a layer of heat fusible polymer over the metal layer and margin portion.
1 more element
A metallized film comprising:
- a dielectric film;
- a metal layer deposited on a portion of a surface of the dielectric film, wherein the surface of the dielectric film upon which the metal layer is deposited has a margin portion which is free of deposited metal;
- and
- a layer of heat fusible polymer on a surface of the dielectric film opposite the surface upon which the metal layer was deposited.
1 more element
A metallized film comprising:
- a dielectric film;
- a first metal layer deposited on a portion of a first surface of the dielectric film, wherein the first surface has a first margin portion which is free of deposited metal;
- a second metal layer deposited on a portion of a second surface of the dielectric film, wherein the second surface has a second margin portion which is free of deposited metal and is located on an opposite edge of the dielectric film from the first margin portion;
- and
- a layer of heat fusible polymer on at least one of the first and second surfaces of the dielectric film.
