6 FAQs about [Film capacitor design formula]
How do film capacitors work?
Film capacitors are build up by two electrodes (the capacitor plates) with plastic dielectric material in between. The type of electrode used determines whether the capacitor is a metalized film or film / foil type. In metalized types, the very thin electrode is evaporated on the plastic dielectric material.
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 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.
How do you know if a capacitor is a metalized film or foil?
The type of electrode used determines whether the capacitor is a metalized film or film / foil type. In metalized types, the very thin electrode is evaporated on the plastic dielectric material. The thin metalized electrodes have a thickness of approximately 10 nm to 50 nm.
How to choose a metallized film capacitor?
struction. Here’s how to choose. For a metallized film capacitor, the capacitor plates are aluminum sprayed onto the dielectric fi m by thin-film vacu-um deposition. Compared to making the capacitor with sep-arate foil and film sheets, met-allizing enables smaller size, lighter weight, lower cost per microfarad and self-healing, but it also
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.
