The self-healing affect of metallized capacitors
The self-healing affect of metallized capacitors Metallized capacitors offer the advantages of volume efficiency and self-healing. Self-healing is the ability of a metallized capacitor to clear a fault area where a momentary short occurs due to dielectric breakdown under voltage. The conditions that lead to a fault vary.
