Abstract: A wet electrolytic capacitor is provided. The capacitor includes a planar anode formed from a pressed and sintered powder, a cathode that includes a metal substrate that is coated with an electrochemically-active material, and a working electrolyte in communication with the planar anode and cathode. The planar anode has a recessed portion formed in at least one of its surfaces. The capacitor also includes at least one restraint that is in contact with the recessed portion and has a shape that generally corresponds with a shape of the recessed portion. The recessed portion of the planar anode allows for stabilization of the planar anode with via a restraint without increasing the dimensions of the capacitor.
