Crimped leadwire for improved contact with anodes of a solid electrolytic capacitor

A solid electrolytic capacitor that comprises a capacitor element, the capacitor element comprising:

• a sintered, porous anode body, wherein a lead assembly is embedded within the anode body, the lead assembly comprising a first lead wire, wherein the first lead wire comprises at least one notch having a length and a width, wherein the notch is located on an embedded portion of the first lead wire, further wherein the notch is an indentation in the first lead wire, wherein the first lead wire has a length of from about 100 micrometers to about 120 millimeters and a width of form about 20 micrometers to about 1000 micrometers, further wherein the length at the first lead wire is from about 1.5 to about 30 times the length of the notch and the width of the first lead wire is from about 1.05 to about 7 times the width of the notch, the first lead wire extending from a surface of the anode body in a longitudinal direction;
• a dielectric layer overlying the sintered porous anode body;
• and
• a cathode overlying the dielectric layer that includes a solid electrolyte.
