ABSTRACT:
A metallized film capacitor includes an aromatic ester dielectric fluid including 2.0-5.0% by weight of an epoxide in an aromatic ester such as dioctyl phthalate. Utilizing such a particular amount of epoxide results in a substantial performance improvement under high temperature and voltage conditions, providing a metallized film capacitor of reduced size and cost.
