Abstract
An electrolytic capacitor includes a metal case, a porous pellet anode disposed within the metal case, an electrolyte disposed within the metal case, and a cathode element formed of an electrophoretically deposited metal or metal oxide powder of a uniform thickness disposed within the metal case and surrounding the anode. A method of manufacturing an electrolytic capacitor includes providing a metal case, electrophoretically depositing on the metal can a refractory metal oxide to form a cathode element, and placing a porous pellet anode and an electrolyte within the can such that the cathode element and the anode element being separated by the electrolyte.
