Abstract
A capacitor, and method of making a capacitor, is provided wherein the capacitor has exceptionally high break down voltage. The capacitor has a tantalum anode with an anode wire attached there to. A dielectric film is on the tantalum anode. A conductive polymer is on the dielectric film. An anode lead is in electrical contact with the anode wire. A cathode lead is in electrical contact with the conductive polymer and the capacitor has a break down voltage of at least 60 V.
