Title:
FILM CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2016/052303
Kind Code:
A1
Abstract:
The present invention is a film capacitor which comprises a dielectric film and a metal layer, and which is characterized in that: the dielectric film is a resin film that is obtained by stretching an unstretched film that is obtained using a crystalline hydrogenated product of a dicyclopentadiene ring-opening polymer and subsequently subjecting the stretched film to a heat treatment; the resin film has a softening point of 250-320°C, a thermal shrinkage of 0.01-5.0% after being heated at 200°C for 10 minutes, a tan δ of 0.0001-0.0010 and a coefficient of static friction of 0.01-1.00. The present invention provides a film capacitor which comprises, as a dielectric film, a resin film that has excellent heat resistance, withstand voltage characteristics and workability.
