<p>A solid electrolytic capacitor 30 operable under the extreme conditions of high temperature and humidity levels is described. The capacitor contains a capacitor element 33 that includes a sintered porous anode body, a dielectric (not shown) that overlies the anode body 40, and a solid electrolyte 44 that overlies the dielectric. The solid electrolyte 44 contains a conductive polymer ie a substituted polythiophene, and an organometallic coupling agent such as an organosilane. The capacitor 30 also contains a moisture barrier layer 63 that may overlie the solid electrolyte 44 and is formed from a hydrophobic elastomer ie a silicone, that has a low surface energy, so that it is not readily wettable by an aqueous medium.</p> |
