Abstract: An improved capacitor is provided. The capacitor comprises an anode comprising a pressed and sintered, preferably tantalum, powder wherein the anode has edge surfaces and parallel major surfaces. The anode further comprises a first set of parallel surface protrusions and a second set of parallel surface protrusions on each parallel major surface wherein the first set of parallel surface protrusions and second set of parallel surface protrusions are not parallel and form a well therebetween. An anode wire extends from an edge surface of the edge surfaces. A dielectric is on the anode and a conductive polymer on said dielectric.
