ABSTRACT:
A process for the accelerated aging and impregnation of electrolytic capacitors having formed anodes is carried out in two stages. In the first stage, the capacitors are loaded into a centrifuge, a voltage less than final aging voltage is applied, the pressure within the centrifuge is reduced, the centrifuge is started, and then electrolyte is admitted to impregnate the capacitors. When the capacitors are fully impregnated, the aging voltage is increased to the desired final value.
