Patent number: 9859065Abstract: An electrolytic capacitor is disclosed having a housing in an arced-trapezoidal shape. Disposed within the housing are one or more anodes, one or more cathodes, one or more separators disposed between anodes that are adjacent anodes cathodes, and an electrolyte disposed around the one or more anodes, the one or more cathodes, and the one or more separators within the housing. The housing of the electrolytic capacitor includes front and back walls shaped as arced-trapezoids and four sidewalls that substantially follow the outline of the front and back walls. The electrolytic capacitor is configured to connect in series with one or more electrolytic capacitors of the same shape to form a capacitor assembly. In the capacitor assembly, electrolytic capacitors are placed such that sidewalls are adjacent to each other to form a D-shaped capacitor assembly.Type: GrantFiled: August 30, 2016Date of Patent: January 2, 2018Assignee: PACESETTER, INC.Inventors: Wisit Lim, Ralph Jason Hemphill, Troy L.
