The metallized polypropylene film capacitor produced by Anhui Saifu Electronics Co., Ltd. is a capacitor formed by winding polypropylene film as the dielectric and the zinc-aluminum metallized layer by physical vapor deposition as the conductive plates. It has the characteristics of non-polarity, stable capacitance, small loss tangent, small ESR and ESL, reasonable size, and self-healing. It can be used in AC and DC occasions in industrial and civil fields, such as DC -Link, DC filter, DC pulse, AC motor, household appliances, low voltage compensation, AC filter, lamps, etc.
A capacitor consists of two conductive plates separated by a dielectric. The opposing surfaces of the two conductive plates can hold equal and opposite charges and create an electric field. The dielectric of Saifu's capacitors is polypropylene film, and the conductive plate is metallized layers (zinc-aluminum or pure aluminum layers) by physical vapor deposition (vacuum evaporation). For ease of use, two or more layers of metallized film with lengths of several meters to thousands of meters are wound into capacitor elements. Saifu's capacitors are composed of single to hundreds of capacitor elements according to capacitor specifications.
