Abstract
A printed-circuit-mountable wet-electrolyte capacitor is housed in a cylindrical can. A disc-shaped plastic cover is fitted in the open end of the can and has a through-terminal sealed therein to which the capacitor anode is electrically connected. Another such terminal, or the can, may serve as the cathode terminal. A groove in the periphery of the cover has a rubber o-ring. The o-ring is compressed by rolling and beading the can inwardly to effect a can/cover seal. Elongate metal pieces are held positioned by cavities provided near the periphery of the cover. The cover is fitted into the can and the elongate pieces are welded to the inner lip of the can to stop outward movement of the cover and to serve as mounting means to a printed circuit board.
