Abstract
Abstract A wound capacitor and method therefor having metallized elongated dielectric webs (21, 26). An additional dielectric web (14) is wound about the capacitor roll and forms a protective wrap. The additional web (14) has a pair of metal foil band terminals (11, 12) formed on the side of the additional web (14) remote from the capacitor roll with each band (11, 12) disposed adjacent a respective end of the capacitor roll and extending there beyond. Terminals (40, 42) are bonded to each end of the capacitor.
