Abstract: An improved electrolytic capacitor, and method of making the electrolytic capacitor, is provided. The electrolytic capacitor comprises an anode comprising a dielectric layer on the anode. A primary conductive polymer layer is on dielectric and a mordant layer on the primary conductive layer wherein the mordant layer comprises a mordant compound of Formula A;
wherein:
each of R1-R6 is independently selected from H and —PO(OR7)2 wherein each R7 is independently selected from H, substituted or unsubstituted alkyl of 1-20 carbons, substituted or unsubstituted aryl of 6-20 carbons or an alkylaryl of 7-21 carbons; with the proviso that at least one of R1-R6 is —PO(OH)2. A secondary conductive polymer layer is on the mordant layer.-

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.
