Abstract
An electrolytic capacitor comprising a plurality of polymeric structures molded about the periphery of the anode pellet is described. The polymeric structures contact between a weld strap surrounding the butt seam between mating “clamshell” casing portions and the anode pellet sidewall. That way, the anode pellet is restrained from moving along both an x- and y-axes inside the casing. Having the cathode active material contacting the opposed major casing sidewalls being in a closely spaced relationship with the anode pellet through an intermediate separator prevents movement along the z-axis. The resulting capacitor is particularly well suited for use in high shock and vibration conditions.
