Patent ID: 7224575

Claim:
A capacitor for connection to a component, comprising: a capacitor stack, including: one or more substantially planar cathode layers; one or more substantially planar anode layers having a dielectric thickness less than 1200 nanometers and formed using a process comprising: forming a hydrous oxide layer on the anode layers; anodizing the anode layers in a bath containing an aqueous solution of boric acid and phosphate; passing the anode layers through a borax solution; and reanodizing the anode layers in boric acid phosphate electrolyte, one or more substantially planar separator layers; and a unitary electrolyte; a case with a feedthrough hole and a first aperture sized for passage of the capacitor stack; a lid sealingly substantially conforming to the first aperture and sealingly connected to the first aperture; and a feedthrough assembly connected to the capacitor stack and passing through a second aperture of the case and sealingly connected to the feedthrough hole, wherein the case is filled with the unitary electrolyte, and the capacitor is adapted to deliver to the component 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 620 volts.
