Abstract: An AC wound metallized film capacitor which has a tab connected to each electrode utilizes a unitary spacer which encompasses the wound section isolating the section from a metal housing and the tabs from each other. The spacer is mainly rectangular in shape with a rectangular extension near the end of one long side and a cutout opposite the extension on the opposite long side. The spacer is wrapped around the capacitor section overlapping itself and extends beyond the top and bottom of the section. One tab, which is attached at the bottom of the section, passes between wound layers of the spacer and extends beyond the upper end of the section. The spacer extending beyond the bottom edge of the section is folded and sealed. The rectangular extension of the spacer isolates the bottom tab from the top of the section.
