Abstract
An electrical component employing a metalized composite film with a heat-seal layer is disclosed. The use of the heat-seal layer in the disclosed configuration allows a wound film capacitor integral with a primary coil to be made without there being a need to impregnate the wound film unit with an epoxy or other resin, thus saving substantial manufacturing time.
