Abstract: A solid electrolytic capacitor is provided that contains a casing material that encapsulates the capacitor element. The casing material is formed from a curable resinous matrix that has a coefficient of thermal expansion of about 42 ppm/° C. or less at a temperature above the glass transition temperature of the resinous matrix. Further, the capacitor exhibits an initial equivalence series resistance of about 200 mohms or less as determined at an operating frequency of 100 kHz and temperature of 23° C., and the ratio of the equivalence series resistance of the capacitor after being exposed to a temperature of 125° C. for 560 hours to the initial equivalence series resistance of the capacitor is about 2.0 or less.

Abstract: A capacitor assembly that comprises a solid electrolytic capacitor element is provided. The capacitor assembly also comprises a casing material that encapsulates the capacitor element, an anode termination that is in electrical connection with the anode body and contains a portion that is positioned external to the casing material, and a cathode termination that is in electrical connection with the solid electrolyte and contains a portion that is positioned external to the casing material. A first hydrophobic coating is disposed in contact with the casing material and the external portion of the anode termination and a second hydrophobic coating is disposed in contact with the casing material and the external portion of the cathode termination.

Abstract: A capacitor assembly that is capable of performing well under the conditions of high humidity (e.g., 60% relative humidity) is provided. The capacitor assembly comprises a solid electrolytic capacitor element that contains a sintered porous anode body, a dielectric that overlies the anode body, and a solid electrolyte that overlies the dielectric. An anode termination is in electrical connection with the anode body and a cathode termination is in electrical connection with the solid electrolyte. A first coating is disposed on at least a portion of the anode termination that contains an organometallic compound and a second coating is disposed on at least a portion of the cathode termination that contains an organometallic compound. Further, a casing material encapsulates the capacitor element and leaves exposed a mounting surface of the anode termination and the cathode termination.
