    摘要： A capacitor of hybrid construction is disclosed comprising a single cathode and multiple anode combination utilizing a variety of anode foils selected for their ability to achieve optimal performance in selected areas of the construction of a spiral would capacitor and blended in a fashion to create maximum energy density and minimum open space. In addition, a method is claimed for reducing open space left by a mandrel in producing spiral wound capacitors.

    摘要： A multiple anode capacitor (10) having offset terminal leads or strips which maximizes capacitance achieved per volume occupied by the capacitor. More specifically, the invention including a multiple anode aluminum electrolytic capacitor including a cylindrical casing (42), a header (45) crimped to the open end of the casing, the header including a primary anode terminal (41) and a primary cathode terminal (44). Disposed within the casing is a wound or coiled capacitor body (28) having plural anode foils (11, 12, 13), a capacitor foil (14), and dielectric paper separator layers (15, 16) disposed between the cathode and the anodes. In a preferred embodiment, three juxtapositioned anode foils are used, the foils being made from a high purity porous aluminum foil. In addition, each of the dielectric paper separator layers is formed of two kraft capacitor tissue papers (15a, 15b, 16a, 16b). Leads, or terminal strips, are attached to each of the anode or cathode foils, the attaching section of each of the leads being offset from the other attaching sections (21a, 22a, 23a, 24a) when the foils are wound together. The leads of the anode foils are connected to the primary anode terminal and the lead of the cathode foil is connected to the primary cathode terminal. A suitable electrolyte (47) permeates the wound capacitor body.
