| 1. A method for forming a capacitor comprising:
forming an anode from a valve metal;
forming a dielectric on the anode to form a dielectric covered anode;
dipping said dielectric covered anode into a slurry of intrinsically conductive polymer;
drying said intrinsically conductive polymer; and
providing terminations in electrical contact with said anode and said intrinsically conductive polymer;
wherein said capacitor has a breakdown voltage of at least 60V.
