Abstract
The present invention relates to an improvement in a metallized film capacitor of wound-type and stacked-type which has been proposed to provide the capacitor with a protection function, i.e. an additional self-healing ability, at the time of dielectric breakdown. The vapor-deposited metal electrode of the capacitor is splitted into segments so that the capacitor itself can prevent a smoke-emitting or burning failure from actually occurring. The present invention improves the reliability of such the protection function by forming narrow current paths on the vapor-deposited metal electrode along a zone which makes it connect with the external connecting member. It also minimizes the loss in static capacitance and in material.
