ABSTRACT:
A metallized wound capacitor which includes first and second dielectric webs. A first electrode having first and second portions is metallized on the first face of the first web. A second electrode having first and second portions is metallized on the first face of the second web. Either the first electrode, the second electrode, or both, are included of a plurality of spaced apart segments interconnected by wirings. 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.
