Beschreibung
Zusammenfassung:	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 solid electrolyte that overlies the dielectric that includes conductive polymer particles that contain a complex formed from a thiophene polymer and a copolymer counterion, and an external polymer coating that overlies the solid electrolyte and includes conductive polymer particles. L'invention concerne un condensateur électrolytique solide contenant un élément de condensateur. L'élément de condensateur contient un corps d'anode poreux fritté, un diélectrique qui recouvre le corps d'anode, un électrolyte solide qui recouvre le diélectrique qui comprend des particules polymères conductrices qui contiennent un complexe formé à partir d'un polymère thiophène et d'un contre-ion copolymère, et un revêtement polymère externe qui recouvre l'électrolyte solide et comprend des particules polymères conductrices.
