摘要: A wet electrolytic capacitor that contains an anode formed from anodically oxidized sintered porous body and a fluidic working electrolyte is provided. The casing metal substrate coated electrochemically-active material. Through unique controlled combination of features relating to the configuration sealing assembly, present inventor has discovered good electrical properties (e.g., ESR stability) can be achieved at relatively high temperatures. One feature help achieve such stability presence dielectric layer on cathode within thickness range. In other embodiments, assembly may employed hermetic seal glass-to-metal seal) elastomeric barrier high-temperature
