Self-healing of metallized film capacitors
Metallized film capacitors have "self-healing" properties, which are not available from film/foil configurations.[11] When sufficient voltage is applied, a point-defect short-circuit between the metallized electrodes vaporizes due to high arc temperature, since both the dielectric plastic …
