Abstract
A solid electrolyte tantalum capacitor comprises a porous tantalum body, a tantalum oxide film grown over the surfaces of the body, and an overlying coating of manganese dioxide wherein a conducting member is partially embedded. The conducting counterelectrode member is of a base metal such as nickel being plated with a noble metal such as gold. Alternatively, the conducting member is a base metal having an adjacent layer of graphite interposed between said base metal and said manganese dioxide. An extended portion of the conducting member serves as the cathode lead.
