Abstract
An electrolytic capacitor with an electrically conductive housing defining a chamber and defining a feed-through aperture providing communication between the interior and exterior of the housing. A number of conductive layers are positioned within the chamber. A feed-through conductor has a first end connected to the layers, an intermediate portion passing through the feed-through aperture, and an elongated external portion extending externally from the housing and terminating at a free end. An insulative sleeve has a first portion closely received within the feed-through aperture and closely receiving the intermediate portion of the feed-through member and has a second elongated portion extending externally from the housing and closely receiving at least a portion of the external portion of the conductor element, so that only a remaining portion of the conductor element is exposed, and is spaced apart from the housing by the length of the second elongated portion.
