Patent ID: 8477479

Claim:
A planar anode for use in a wet electrolytic capacitor, wherein the anode comprises an anodically oxidized pellet formed from a pressed and sintered powder, wherein the anode further comprises a leadwire containing only a first portion and a second portion, wherein the first portion extends outwardly from the pellet in a longitudinal direction and the second portion is embedded within the pellet, wherein the second portion is oriented at an angle of about 40° to about 120° relative to the longitudinal direction such that the second portion contains a single bend, wherein the ratio of the length of the second portion of the leadwire to the length of the anode is from about 0.1 to about 0.6, wherein the planar anode has a thickness of about 5 millimeters or less, and wherein the ratio of the length of the anode to the thickness of the anode is from about 5 to about 50.
