An electronic unit includes an electrolytic capacitor, a covering resin layer, and electronic components. The electrolytic capacitor is on an upper surface of an insulating substrate. The covering resin layer covers the upper surface of the insulating substrate and the electronic components. Part of the covering resin layer serves as an electrolytic capacitor covering portion. The electrolytic capacitor covering portion includes an outer peripheral covering portion that covers an outer peripheral surface of the electrolytic capacitor and a top covering portion that covers a top portion of the electrolytic capacitor. A thin wall groove is formed in the top covering portion. The outer peripheral covering portion extends upward beyond the top covering portion by a height h. The top covering portion easily breaks at the thin wall groove so that an explosion-proof valve easily operates. A region corresponding to the height h creates an operating space of the explosion-proof valve.

A capacitor, an assembly comprising a capacitor and a busbar and a method for manufacturing a capacitor are disclosed. In an embodiment a capacitor includes a winding element and a terminal having a first part of a first material and a second part of a second material, the second material being different than the first material, wherein the first part is electrically contacted to the winding element, and wherein the second part is an external contact of the capacitor.

In an embodiment an electrolytic capacitor includes a covering element configured to close an opening of a can comprising a capacitor element. A connection element comprises a lead tab for applying an electrical signal to the capacitor element and a rivet having a first head to fix the lead tab to the covering element. The connection element includes an upper washer arranged between the first head of the rivet and the lead tab. The lead tab has a first section having a first opening and a second section having a second opening. The lead tab is folded such that the first opening and the second opening of the lead tab are arranged above each other. The rivet is arranged in the first and second openings of the lead tab and in an opening of the upper washer.

A separator that includes a porous polymer substrate, a first porous coating layer and a second porous coating layer. First inorganic particles contained in the first porous coating layer have a lower hardness as compared to the second inorganic particles contained in the second porous coating layer. Since the separator is provided with at least two porous coating layers including inorganic particles having a different hardnesses, it is possible to increase the dielectric breakdown voltage, and thus to provide a battery with improved safety. It is also possible to reduce deformation of the separator caused by heat or pressure.

A capacitor is disclosed. In an embodiment a capacitor includes a container and a capacitor winding arranged inside the container, wherein the container comprises at least three ribs projecting into the container and located in the container at a transition from a container wall to a container base, wherein the container comprises at least one bead in the container wall, wherein the at least one bead reach around a circumference of the container, wherein the capacitor winding abuts the bead, and wherein the capacitor winding is deformed by the rips.
