Abstract
A zinc metallized film capacitor includes a dielectric fluid comprising epoxidized soybean oil having at least one epoxy group per molecule, preferably four epoxy groups per molecule. Utilizing epoxidized soybean oil with zinc metallization results in a substantial performance improvement under high temperature and high voltage conditions, providing a zinc metallized film capacitor of reduced size and cost. In addition, the epoxidized soybean oil is relatively non-toxic, reducing environmental concerns.
