6 FAQs about [What is capacitor foil ]
How does a foil capacitor work?
An inductive film foil capacitor is coiled so that the aluminum foils are in the middle of the two films. The aluminum foils are joined to one another by a leading wire that holds the entire coil together. In a noninductive fil foil capacitor, the aluminum foils are positioned so that each foil is partially exposed to the films.
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.
Can a film capacitor be made smaller than a foil electrode?
Instead of using foil as electrode, this type of film capacitor uses a layer of metal (aluminum, zinc, etc.) deposited on the plastic film itself to form an internal electrode. Because the deposited film is very thin, the capacitor can be made smaller than the foil electrode type.
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.
