SOLID ELECTROLYTIC CAPACITOR FOR USE UNDER HIGH TEMPERATURE AND HUMIDITY CONDITIONS

摘要

A solid electrolyte capacitor capable of exhibiting excellent electrical properties even under extreme conditions of high temperature and high humidity is provided. More particularly, the capacitor contains a capacitor component comprising a sintered porous anode body, a dielectric overlying the anode body, and a solid electrolyte overlying the dielectric. The solid electrolyte contains a conductive polymer and an organometallic coupling agent. The capacitor also contains a moisture barrier layer formed from a hydrophobic elastomer having a low surface energy that overlies the solid electrolyte and makes it not readily wettable by an aqueous medium.
