Abstract: A module of capacitor assemblies is provided. To increase the capacitance and efficiency of the module, capacitor assemblies may be stacked. A variety of aspects of the module are controlled in the present invention, including the number of capacitor assemblies, the manner in which the capacitor assemblies are arranged and incorporated into the module, and the manner in which the capacitor assemblies are formed. For example, the anode terminations of each capacitor assembly are electrically connected and the cathode terminations of each capacitor assembly are electrically connected. The capacitance and efficiency of the module can be improved while maintaining the footprint of a single capacitor assembly.

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.

Abstract: A capacitor assembly that is capable of exhibiting good properties under hot conditions. The ability to perform under such conditions is due in part to the use of an intrinsically conductive polymer in the solid electrolyte that contains repeating units having the following formula (I): wherein, R is (CH2)a—O—(CH2)b; a is from 0 to 10; b is from 1 to 18; Z is an anion; and X is a cation. The resulting capacitor assembly may exhibit excellent electrical properties even when exposed to high temperatures.

Abstract: A capacitor that is capable of exhibiting good electrical properties even under a variety of conditions is provided. More particularly, the capacitor contains a sintered porous anode body, a dielectric that overlies the anode body, and a solid electrolyte that overlies the dielectric. The solid electrolyte contains an inner layer and an outer layer, wherein the inner layer is formed from an in situ-polymerized conductive polymer and the outer layer is formed from pre-polymerized conductive polymer particles. Further, the in-situ polymerized conductive polymer is formed from an alkylated thiophene monomer.
