Abstract: A capacitor assembly that is capable of performing under extreme conditions, such as at high temperatures and/or high voltages, is provided. The ability to perform at high temperature is achieved in part by enclosing and hermetically sealing the capacitor element within a 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 element. Furthermore, the present inventors have also discovered that the ability to perform at high voltages can be achieved through a unique and controlled combination of features relating to the formation of the anode, dielectric, and solid electrolyte. For example, the solid electrolyte is formed from a combination of a conductive polymer and a hydroxy-functional nonionic polymer.

Abstract: A capacitor assembly configured to effectively dissipate heat when exposed to a high ripple current is provided. The assembly includes a plurality of capacitor elements, each including an anode body and lead, a dielectric layer overlying the anode body, and a solid electrolyte. Each capacitor element is defined by upper and lower major surfaces, first opposing minor surfaces, and second opposing minor surfaces. The major surfaces each have a surface area greater than that of each of the minor opposing surfaces. A hermetically sealed housing having a length, width, and height defines an interior cavity within which the plurality of capacitor elements are positioned. The ratio of the length to the height ranges from about 2 to about 80. Further, the lower major face of each capacitor element faces a lower wall of the housing, where the lower wall is defined by the housing's length and width.

Abstract: A wet electrolytic capacitor that contains a casing within which is positioned an anode formed from an anodically oxidized sintered porous body and a fluidic working electrolyte is provided. The casing contains a conductive coating disposed on a surface of a metal substrate. The casing contains a metal substrate coated with a conductive coating. The conductive coating contains a conductive polymer layer formed through anodic electrochemical polymerization (“electro-polymerization”) of a colloidal suspension on the surface of the metal substrate. The conductive coating also contains a precoat layer that is discontinuous in nature and contains a plurality of discrete projections of a conductive material that are deposited over the surface of the metal substrate in a spaced-apart fashion so that they form “island-like” structures.

Abstract: 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.
