摘要： A capacitor assembly that is stable under extreme conditions is provided. A capacitor assembly that is capable of achieving a high capacitance and yet remain thermally and mechanically stable under extreme conditions. Even at high capacitance values, good mechanical stability can be achieved by connecting multiple individual capacitor elements to the housing of the assembly. Without intending to be limited by theory, it is believed that the use of multiple elements increases the surface area over which the elements are connected to the housing. Among other things, this allows the elements to dissipate vibrational forces incurred during use over a larger area, which reduces the likelihood of delamination. The capacitor elements are also enclosed and hermetically sealed within a single housing in the presence of a gaseous atmosphere that contains an inert gas, thereby limiting the amount of oxygen and moisture supplied to the solid electrolyte of the capacitor elements. Through the combination of the features noted above, the capacitor assembly is able to better function under extreme conditions.

摘要： A capacitor assembly for use in high voltage and high temperature environments is provided. More particularly, the capacitor assembly includes a capacitor element containing an anodically oxidized porous, sintered body that is coated with a manganese oxide solid electrolyte. To help facilitate the use of the capacitor assembly in high voltage (e.g., above about 35 volts) and high temperature (e.g., above about 175° C.) applications, 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 moisture supplied to the manganese dioxide. In this manner, the solid electrolyte is less likely to undergo an adverse reaction under extreme conditions, 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.
