Abstract
Abstract An aluminum electrolytic capacitor is housed in an aluminum can whose cover is made of two aluminum plates lying in the same plane, and insulated from the can and from each other by insulative layers of butyl rubber. The capacitor foils are connected to a stripline which is composed of two aluminum plates separated by a layer of butyl rubber. Each stripline plate is at right angles to one of the cover plates.
