Abstract
A solid electrolytic capacitor is described which comprises an anode, a dielectric on the anode and a cathode on the dielectric. A conductive coating is on the cathode wherein the conductive layer comprises an exterior surface of a first high melting point metal. An adjacent layer is provided comprising a second high melting point metal, wherein the first high melting point metal and the second high melting point metal are metallurgically bonded with a low melting point metal.
