Abstract: The capacitor includes, between an anode and a cathode, a separator formed by at least one porous polymer film and at least one absorbent paper sheet impregnated with an electrolyte, the polymer film being disposed against the anode. The preferred polymer materials are polypropylene and polyester (especially polybutylene terephthalate).
Abstract: An electrolytic filter capacitor has two terminals in a molded insulating cover. The terminals are identical and each is shaped as a polyhedron. The terminals which have means for connection to inner parts of the capacitor and to outer members such as bus bars occupy 15 - 40% of the exposed area of the cover. Each terminal has a plane of symmetry in the direction of maximum size which ae parallel and as closely spaced to each other as insulation requirements permit.
