Low Profile Multi-Anode Assembly in Cylindrical Housing

摘要

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. A metal cylindrical housing having a lid and base, where the lid has a diameter in an −x direction and the metal cylindrical housing has a height in a −z direction, defines an interior cavity within which the plurality of capacitor elements are arranged about a central axis running along the −z direction. The ratio of the diameter to the height of the base ranges from about 1.5 to about 20. Further, the metal cylindrical housing is hermetically sealed.
