Abstract
The capacitor has a monolithic anode and at least one anode lead wire extending from the anode. At least one sacrificial lead wire extends from the anode. A dielectric layer is on said anode and a cathode layer is on the dielectric layer. The anode lead wire is in electrical contact with the anode and a cathode lead is in electrical contact with the cathode.
Claims14
A method for forming a capacitor comprising:
- pressing a powder into a monolith comprising at least one anode lead wire and a sacrificial lead wire extending there from;
- engaging said sacrificial lead with a transport device;
- transporting said anode to a dielectric formation station wherein dielectric is formed on said pressed anode forming an anodized anode;
- transporting said anodized anode to a cathode application station wherein a cathode is formed on said dielectric;
- and
- disengaging said sacrificial lead wire from said transport device.
