6 FAQs about [Capacitor film material localization]
What is a metallized film capacitor?
Metallized film capacitors are made of two metallized films with plastic film as the dielectric. A very thin (~ 0.03 μm ) vacuum-deposited aluminum metallization is applied to one or both sides to serve as electrodes.
What are plastic film capacitors?
Plastic film capacitors are generally subdivided into film/foil capacitors and metalized film capacitors. Film / foil capacitors basically consist of two metal foil electrodes that are separated by an insulating plastic film also called dielectric. The terminals are connected to the end-faces of the electrodes by means of welding or soldering.
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.
Which polymer is best for film capacitors?
Polymers in Film Capacitors - The Next Generation Material is available! Polypropylene is the polymer of choice for most film capacitors, but there is an inherent high temperature limit for its usage. New polymer materials are therefore required to overcome these temperature limitations.
