What are film capacitors?

The "film capacitors" were developed together with the growing market of broadcast and electronic equipment technology in the mid-20th century. These capacitors are standardized under the rules of IEC/EN 60384-1 "Capacitors for use in electronic equipment" and different "film materials" have their own sub standards, the IEC/EN 60384- n series.

Who makes metallized film capacitors?

Wherever innovative film capacitors are in use, Steiner is the worldwide leading manufacturer of high quality metallized capacitor grade films of BOPP, PET, PPS, PEN, Paper and other dielectrics with single or double-sided metallization in high-vacuum technology and roll configuration.

Which is the largest manufacturer of plastic film capacitors in India?

The present capacity of 1.2 billion pcs/annum makes Deki the largest manufacturer of plastic film capacitors in India. Its capacitors are currently exported to Europe, Hong Kong, China, Middle East, Malaysia, Philippines and South Korea. Deki has been growing at an average annualised growth rate of 29 per cent year on year since 1989-90.

What are the raw materials for capacitor films?

The preferred choice of raw materials for capacitor films are polypropylene (PP) and polyethylene terephthalate (PET). PP is independent of frequency and temperature (<105°C) and has a high impulse stability – therefore it can be used in AC and DC applications.

What is a heavy-duty film capacitor?

Especially for applications with high current pulse loads or high AC loads in electrical systems, heavy-duty film capacitors, here called "power capacitors", are available with dielectric ratings of several kilovolts. But the manufacture of film capacitors does have a critical dependency on the materials supply chain.

What are the different types of plastic film capacitors?

There are two different types of plastic film capacitors, made with two different electrode configurations: Film/foil capacitors or metal foil capacitors are made with two plastic films as the dielectric. Each is layered with a thin metal foil, usually aluminum, as the electrodes.
