Abstract

A capacitor winding for a capacitor has a layer stack that is limited by two end faces in a longitudinal direction and by one or more lateral surfaces that extend transverse to the longitudinal direction. The stack has electrode layers and parting layers proceeding in the longitudinal direction, and has a single-ply sheath of an electrically insulating material that covers the lateral surfaces of the layer stack gap-free and that has a projecting section at an end face. The sheath can be especially advantageously implemented as a heat shrinkable tube or hose that protects the capacitor winding against damage upon insertion into a housing of the capacitor.
