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.
