Title:
FILM CAPACITY AND RESIN FILM
Document Type and Number:
Japanese Patent JP2022045538
Kind Code:
A
Abstract:
To provide a film capacitor that includes a resin film, of which the coefficient of static friction is low and the slipperiness is high.SOLUTION: A film capacitor 100 comprises a dielectric film 110, and a metal layer 120 provided on at least one surface of the dielectric film 110. The dielectric film 110 is composed of a resin film 1 having a first surface 11 and a second surface 12 in the thickness direction. The resin film 1 includes a first rein layer 21 and a second resin layer 22 one surface of which constitutes the first surface 11 of the resin film 1. The second resin layer 22 contains a plurality of inorganic particles 31. The content of inorganic particles 31 in the whole of the film, with the dielectric film 110 and the metal layer 120 combined together, is 1.2% by weight to 2.7% by weight, both ends inclusive. Assuming that D1 represents the particle diameter of inorganic particles 31 protruding from the first surface 11 of the resin film 1 and H1 represents a protrusion height from the first surface 11, the ratio H1/D1 of the protrusion height H1 to the particle diameter D1 is 0.2 and over to less than 1.SELECTED DRAWING: Figure 2
