A wound electrolytic capacitance section is housing within a metal can having a plurality of circumferential indentations or ribs. The uppermost rib provides a seat for the capacitor cover. The lowermost rib determines the depth to which the section extends into the can and provides bottom support for the section. At least one intermediate rib provides lateral support for the section and prevents its lateral movement.

Metal-cased electrolytic capacitor

A plurality of electrolytic capacitor sections are sealed within a common cube-like case. An internal wall divides the case into isolated chambers. Upon sealing of the case, the assembly takes up substantially no more space on a circuit board than an individual capacitor of the prior art. Each capacitor chamber has its own vent located in the case at the junction of a side wall (parallel to the internal wall) and the top wall by means of a bevel which reduces the walls to the desired vent thickness.

Electrolytic capacitor assembly

A mounting ring is secured in the mouth end of a capacitor casing by being engaged under the rolled-over rim of the fully sealed capacitor.
