Abstract: A solid electrolytic capacitor including a capacitor element, a first anode lead, a second anode lead, and a carrier wire. The capacitor element includes a sintered, porous anode body; a dielectric layer overlying the sintered, porous anode body; and a cathode overlying the dielectric layer that includes a solid electrolyte. The first and second anode leads each have an embedded portion positioned within the anode body and an external portion extending longitudinally from a surface of the anode body in an x-direction, while the carrier wire is positioned external to the anode body. Further, a first portion of the carrier wire is connected to the external portions of the first and second anode leads, while a second portion of the carrier wire extends longitudinally away from the surface of the anode body in the x-direction. Such an arrangement reduces the ESR and leakage current of the capacitor.

Abstract: A capacitor assembly for use in high voltage and high temperature environments is provided. More particularly, the capacitor assembly includes a solid electrolytic capacitor element containing an anode body, a dielectric overlying the anode, and a solid electrolyte overlying the dielectric. To help facilitate the use of the capacitor assembly in high voltage applications, it is generally desired that the solid electrolyte is formed from a dispersion of preformed conductive polymer particles. In this manner, the electrolyte may remain generally free of high energy radicals (e.g., Fe2+ or Fe3+ ions) that can lead to dielectric degradation, particularly at relatively high voltages (e.g., above about 60 volts). Furthermore, to help protect the stability of the solid electrolyte at high temperatures, the capacitor element is enclosed and hermetically sealed within a housing in the presence of a gaseous atmosphere that contains an inert gas.

Abstract: A capacitor assembly for use in high voltage and high temperature environments is provided. More particularly, the capacitor assembly includes a solid electrolytic capacitor element containing an anode body, a dielectric overlying the anode, and a solid electrolyte overlying the dielectric. To help facilitate the use of the capacitor assembly in high voltage applications, it is generally desired that the solid electrolyte is formed from a dispersion of preformed conductive polymer particles. In this manner, the electrolyte may remain generally free of high energy radicals (e.g., Fe2+ or Fe3+ ions) that can lead to dielectric degradation, particularly at relatively high voltages (e.g., above about 60 volts). Furthermore, to help protect the stability of the solid electrolyte at high temperatures, the capacitor element is enclosed and hermetically sealed within a housing in the presence of a gaseous atmosphere that contains an inert gas. It is believed that the housing and inert gas atmosphere are capable of limiting the amount of oxygen and moisture supplied to the conductive polymer of the capacitor. In this manner, the solid electrolyte is less likely to undergo a reaction in high temperature environments, thus increasing the thermal stability of the capacitor assembly. In addition to functioning well in both high voltage and high temperature environments, the capacitor assembly of the present invention may also exhibit a high volumetric efficiency.

Abstract: An electrolytic capacitor is provided that contains a capacitor element, a case, and anode and cathode terminations having first and second external components. The first external components are perpendicular to a lower surface of the case, while the second external components are parallel to the lower surface of the case and extend outwardly away from the front and rear surfaces of the case, respectively. Further, the second external components are mounted to a circuit board such that at least a portion of the capacitor is embedded in the board and such that the second external components are parallel to and in contact with a mounting surface of the circuit board. The particular arrangement of the external components of the terminations stabilizes the capacitor when it is embedded into the board to minimize flexing against the board and cracking or delamination of the capacitor.
