A capacitor structure for dissipating heat, for example, generated by high ripple currents. The capacitor includes an outer casing of substantially annular cross section comprising an outer side wall, a bottom and an interior tube integrally formed from a substantially continuous piece of thermally conductive material. A capacitor winding of substantially annular cross section is disposed within the outer casing which is sealed at a top. The capacitor winding may be in close thermal contact with the inner tube, the bottom and the outer side wall to improve heat dissipation.

High ripple current 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 capacitor assembly has a wound and flattened non-extended foil capacitor section with at least one electrode tab connected to each electrode and is enclosed in a case having an insulating cover and an insulating base. Conductive members are secured to said base by conductive means which extend through the members and the base; one end of each conductive means is covered by a folded portion of the conductive member and welded. The electrode tabs are attached by welding to a side portion of the conductive member.
