A solid electrolytic capacitor that comprises a capacitor element, a lead wire, an anode termination, and a cathode termination is provided. The capacitor element contains a sintered porous anode body, a dielectric that overlies the anode body, and a solid electrolyte that overlies the dielectric. Further, the lead wire is in electrical contact with the anode body and contains a first region that is located in proximity to a surface of the capacitor element. The lead wire contains a core that extends outwardly from the surface, and an oxide layer coats at least a portion of the core within the first region. |
