FAQ

1. What are film capacitors used for?

Film capacitors are used in power electronics, filtering, DC link circuits, and signal processing due to their stability and low loss characteristics.

2. What is the difference between polypropylene and polyester film capacitors?

Polypropylene (PP) offers lower loss and better stability, while polyester (PET) provides higher capacitance in a smaller size but with slightly higher loss.

3. What are DC link film capacitors?

DC link capacitors are used in power conversion systems to stabilize voltage and reduce ripple between rectifier and inverter stages.

4. Are film capacitors suitable for high-voltage applications?

Yes, film capacitors are widely used in high-voltage applications due to their excellent dielectric strength and reliability.

5. Do you support sourcing for obsolete film capacitors?

Yes, we provide sourcing services for discontinued or hard-to-find film capacitors and offer alternative solutions when needed.

6. What is your quality assurance policy?

All products come with a 180-day warranty. Customers must provide authorized test reports or visual evidence for any claims within the valid period.
