FAQ

Q: What is film capacitor?

A: Film capacitors are capacitors made of metallized film (e.g. polyester, polypropylene) as a medium by winding or laminating process, which are characterized by high stability and low loss.

Q: What are the main materials for film capacitors?

A: Dielectric materials include polypropylene (PP), polyester (PET); electrode materials are mostly aluminum, zinc or alloy.

Q: What is the difference between film capacitors and electrolytic capacitors?

A: Film capacitors have no polarity, long life, high voltage resistance, suitable for high frequency applications; electrolytic capacitors have large capacity but shorter life, suitable for low frequency filtering.
