Structure and method providing a capacitor connected to a component, including a capacitor stack made from one or more substantially planar cathode layers, one or more substantially planar anode layers, one or more substantially planar separator layers, and a solitary electrolyte. Additionally, the capacitor includes a case with a first aperture sized for passage of the capacitor stack and a second aperture, and one or more conductors connecting the capacitor stack to the component, with at least one conductor passing through the second aperture of the case, the at least one conductor sealingly connected to the second aperture. Further, the capacitor case is filled with a solitary electrolyte, and the capacitor stack is adapted to deliver to electronics from about 5.3 joules per cubic centimeter of capacitor stack volume to about 6.3 joules per cubic centimeter of capacitor stack volume, at a voltage of between about 465 volts to about 565 volts.
