The 450V ceiling fan capacitor is made of metallized polypropylene film sheet with a temperature-resistant, corrosion-resistant plastic housing, rated capacity of 6 mfd, ideal for starting and working single-phase motors in 50Hz/60Hz AC power systems.
Tips: Role of metallized film capacitors
Metallized film capacitors have a so-called self-recovery effect, i.e., if a small part of the electrode is short-circuited due to the fragility of the electrical boundary, the electrode metal around the short-circuited part will be restored to insulation by melting and evaporating a larger area due to the electrostatic energy or short-circuit current carried by the capacitor at that time, so that the capacitor can resume its role as a capacitor again.
