A capacitor is described. A casing for the capacitor comprises a container having a face wall joined to a surrounding sidewall extending to a annular edge defining an open end of the container. An inwardly extending protrusion is located intermediate the face wall and the annular edge at the container open end. A partition plate is supported on the protrusion to thereby provide a first capacitor enclosure bounded by the face wall, the surrounding sidewall and the partition plate. A cover plate is secured to the annular edge to close the open end of the container and provide a second capacitor enclosure bounded by the partition plate, the surrounding sidewall and the cover plate. An anode, for example of tantalum, and a cathode active material, for example of ruthenium oxide, reside in capacitive association with each other inside each of the first and second capacitor enclosures. A working electrolyte is also contained in the capacitor enclosures. Finally, leads extend from each anode through insulative seals structures supported by the casing for making electrical connection to the capacitor.
