Abstract
A solid electrolytic capacitor containing a capacitor element is provided. The capacitor element contains a sintered porous anode body, a dielectric that overlies the anode body, a pre-coat that overlies the dielectric, and a solid electrolyte that overlies the pre-coat. The solid electrolyte includes a conductive polymer having repeating units derived from an aniline monomer having the following general formula (I):
Claims36
A solid electrolytic capacitor comprising a capacitor element, wherein the capacitor element comprises:
- a sintered porous anode body;
