6 FAQs about [Structure of Thick Film Capacitors]
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.
What is a film capacitor?
The capacitor is a device (part) that performs this charging and discharging of accumulated charges as its function. εr : Relative Permittivity 2. Types of (fixed) capacitors 3. Types of Film Capacitors “Miler” ( Du-Pont) is famous.
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 is a film/foil capacitor?
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. Advantages of this construction type are easy electrical connection to the metal foil electrodes, and its ability to handle high current surges.
What is the dissipation factor of film/foil capacitors?
The dissipation factor for film/foil capacitors is lower than for metallized film capacitors, due to lower contact resistance to the foil electrode compared to the metallized film electrode. The dissipation factor of film capacitors is frequency-, temperature- and time-dependent.
What is the capacitance of a plastic film capacitor?
The film/foil variants of plastic film capacitors are especially capable of handling high and very high current surges. Typical capacitance values of smaller film capacitors used in electronics start around 100 picofarads and extend upwards to microfarads.
