FAQS about What are polypropylene capacitors

What is a polypropylene film capacitor?

Polypropylene film capacitors are made of two pieces of plastic film covered with metallic electrodes. There are two main types of dielectric layers.

Why are polypropylene film capacitors used in resonant circuits?

Polypropylene film capacitors are specified because of their low electrical losses and their nearly linear behavior over a very wide frequency range, for stability Class 1 applications in resonant circuits, comparable only with ceramic capacitors.

Is polypropylene a good capacitor?

Tolerance is about 1 percent, so it's pretty precisely near its nominal value. Polypropylene capacitors are used when a better tolerance is needed than what a polyester capacitor can provide. Polypropylene capacitors also have high isolation resistance, which makes them a good choice for coupling and/or storage applications.

Are polystyrene and polycarbonate film capacitors still made?

Even the long-time manufactured polystyrene (PS) and polycarbonate (PC) film capacitors have been largely replaced by the previously mentioned film types, though at least one PC capacitor manufacturer retains the ability to make its own films from raw polycarbonate feedstock.

What is a polycarbonate film capacitor?

Polycarbonate film capacitors are film capacitors with a dielectric made of the polymerized esters of carbonic acid and dihydric alcohols polycarbonate (PC), sometimes given the trademarked name Makrofol. They are manufactured as wound metallized as well as film/foil types.

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.
