Abstract
Official abstract text for this publication.
A metalized film capacitor includes metalized films, each of which is formed of an insulating film made of dielectric, and a vapor deposited metal electrode formed on an upper surface of the insulating film. An end of the vapor deposited metal electrode extends together with an end of the insulating film, and both the ends are connected to an electrode terminal. The vapor deposited metal electrode of the metalized film includes a center region and a low resistance section that is made of Al—Zn—Mg alloy. The low resistance section is disposed at an end of the electrode and is thicker than the center region. This metalized film capacitor has high humidity resistance.
First claim
Opening claim text (preview).
The invention claimed is: 1. A metalized film capacitor comprising: a metalized film including an insulating film made of dielectric material, a first electrode that is a vapor deposited metal electrode disposed on an upper surface of the insulating film; a second electrode disposed on a lower surface of the insulating film, the second electrode facing the first electrode across the insulating film; a first electrode terminal connected to the first electrode; and a second electrode terminal connected to the second electrode, wherein an end of the first electrode and an end of the insulating film extends to be connected to the first electrode terminal, wherein the first electrode includes: a center region away from the end of the first electrode and faces the second electrode across the insulating film; and a low resistance section made of an Al—Zn—Mg alloy disposed at the end of the first electrode, the low resistance section being thicker than the center region, and wherein the low resistance section contains Mg, and a peak of the atomic percentage of the Mg is located a range not greater than 5 nm from a surface of the low resistance section. 2. A metalized film capacitor comprising: a metalized film including an insulating film made of dielectric material, a first electrode that is a vapor deposited metal electrode disposed on an upper surface of the insulating film; a second electrode disposed on a lower surface of the insulating film, the second electrode facing the first electrode across the insulating film; a first electrode terminal connected to the first electrode; and a second electrode terminal connected to the second electrode, wherein an end of the first electrode and an end of the insulating film extends to be connected to the first electrode terminal, wherein the first electrode includes: a center region away from the end of the first electrode and faces the second electrode across the insulating film; and a low resistance section made of Al—Zn—Mg alloy disposed at the end of the first electrode, the low resistance section being thicker than the center region, and wherein the atomic percentage of the Mg contained in the low resistance section is lower than an atomic percentage of the Mg contained in the center region.
