Along with the development of technological level, upgrade cycles of electronics, home appliances, communications and other industries are getting shorter. Film capacitors, with its excellent electrical performance and high reliability, have become essential electronic components to promote upgrading of those industries. In the coming years, along with further development, increasing investment to national power grid construction, railway construction, energy-saving lighting, hybrid cars and other aspects, and upgrade of consumer electronic products by digitalization, informatization, and networking construction, film capacitor market demand will further show a rapid growth trend.
Film capacitors in the world market will be growing at 15~20% speed. The market growth of film capacitor will drive polypropylene electronic film market's rapid growth.
Metallized Film Capacitor
Thin films used by metallized film capacitor include poly ethyl acetate, polypropylene, polycarbonate, etc. In addition to winding type, there is laminated type. Metallized film capacitor has a so-called Self Healing Action. That is, if when the tiny part of the electrodes cause short circuit due to weak electrolyte, electrode metal around parts causing short circuit will raise larger area of dissolving and evaporation and recover insulation due to electrostatic energy or short circuit current of the capacitor, making capacitor recovering its role of capacitor.
Film capacitors used in audio equipments got famous first, with highest popularity. WIMA capacitor, known as "Red Elixir" or "Germany Elixir" is firstly recommended. In early days, WIMA is the only commercially available advanced stuff on the market. Although advances in materials and technology and market demand, various brands of advanced plastic film capacitor have become dazzling, but WIMA shall remain the most well known brand. And the most famous WIMA capacitor is the MKP-10 PP capacitor.
www.film-capacitor.net has been specializing in film capacitor and AC motor run capacitor manufacturing since 1993. All our products are SGS, IEC, ISO9001 and RoHS compliant. For film capacitors, Shanrui's capacitor's dielectric materials are polyester film, polypropylene film and the dielectrod is evaporated metal layer or Aluminum foil or Zinc-Aluminum foil. And the construction is wound or stacked. For ceramic capacitors, Shanrui only focus on high voltage ceramic capacitor, including disc type and screwed type (axial).
