Abstract
A solid cathode electrolytic capacitor and method of making a solid electrolytic capacitor are provided. The capacitor comprises an anode comprising an anode lead and an anode lead extension extending from the anode lead. The anode lead and anode lead extension are joined at a weld region. A dielectric is on the anode and a cathode is on the dielectric.
Claims51
A solid cathode electrolytic capacitor comprising:
- an anode comprising an anode lead;
- an anode lead extension extending from said anode lead wherein said anode lead and said anode lead extension are joined at a weld region wherein said anode lead extension is a valve metal;
- a dielectric on said anode;
- a cathode on said dielectric;
- an encapsulation encapsulating said anode wherein one of said weld region or said anode lead extension extends to a surface of said encapsulation;
- and
- a metallization on said encapsulation wherein said metallization is in electrical contact with said weld region or said anode lead extension.
