Abstract: A wet tantalum capacitor of a dual anode design is described. The anodes are housed in their own casing compartments, which are separated from each other by an intermediate partition. Preferably, the casing comprises two clamshell-shaped members that house respective anodes. The clamshells face each other, but are prevented from direct contact by the intermediate partition. The clamshells are welded to opposite sides of the partition to hermetically seal the casing. Prior to sealing, however, cathode active material is contacted to inner face walls of the clamshells and the opposite sides of the partition. The cathode active material is aligned in a face-to-face relationship with major surfaces of the anodes. Preferably, a polymeric restraining device prevents the anode from contacting the case. The hermetically sealed casing is filled with electrolyte thru a port. The fill port is hermetically sealed to complete the capacitor.

Abstract: A capacitor is described. A casing for the capacitor has a surrounding sidewall extending to opposed first and second open ends. An inwardly extending ledge of the sidewall is intermediate the first and second open ends. A partition plate is supported on the ledge. A first lid is secured to the first annular edge to close the first capacitor compartment bounded by the partition plate, the surrounding sidewall and the first lid, and a second lid is secured to the second annular edge to close the second capacitor compartment bounded by the opposite side of the partition plate, the surrounding sidewall and the second lid. At least one anode resides in each of the first and second capacitor compartments spaced from cathode active material supported on the casing walls facing the anodes. There is also a separator intermediate the anode and cathode. Insulative seals supported by the casing electrically isolate anode leads connected to the respective anodes from the casing serving as a terminal for the cathode. Finally, a working electrolyte is provided in the first and second capacitor compartments in contact with the anodes and cathode active material.

Abstract: A wet tantalum capacitor of either a single anode design or of multiple anode configurations having cathode active material supported on the casing and sealed in its own separator material is described. The separator “covers’ the cathode active material and is adhered directly to the casing. For a multiple anode design, an inner cathode foil positioned between opposed anode pellets is sealed in its own separator bag. Preferably, a polymeric restraining device prevents the anode from contacting the casing. The completed anode/cathode electrode assembly is sealed in the casing, which is filled with electrolyte thru a port. The fill port is hermetically sealed to complete the capacitor.
