Abstract
The invention pertains to a capacitor of a thermostable polymer film type. The polymer used is polyphenylquinoxaline or polyhydantoin. The polymer film may be obtained by casting with organic solutions. The capacitor can also be obtained with supporting films covered with metallizations coated with this thermostable polymer.
