Dielectric fluid for improved capacitor performance

Abstract: A dielectric fluid thai provides improved resistance to device failure m capacitors comprising combinations of certain anthraqiunosxe compounds and scavengers. Capacitors including the dielectric fluid can have a higher discharge inception voltage and can have increased failure threshold voltages in comparison to capacitors made without the combination. Therefore, these capacitors are snore resistant to failures.

Wet Electrolytic Capacitor for Use at High Temperatures

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