ABSTRACT:
The present invention involves a metallized wound capacitor having increased dielectric breakdown voltage which includes first and second dielectric webs. A first electrode having first and second portions, where the first portion is between 5-300 Ohms/square, is metallized on the first face of the first web, to a width less than the width of the first web. A second electrode having first and second portions is metallized on the first face of the second web to a width less than the width of the second web. The first and second electrodes extend from opposing dielectric web longitudinal edges leaving respective bare margins along opposing edges on the respective webs. Each second portion has a width equal to the opposing bare margin less a predetermined tolerance and is thicker than its respective first portion.
