FAQ

Q: How to select a capacitor for scenarios that need to withstand high-frequency pulses?

A: Prefer metalized polypropylene capacitors to support high dv/dt and pulse current.

Q: How to determine whether self-healing function is needed?

A: Self-healing capacitors can improve reliability in scenarios where voltage fluctuations are frequent or where there is a risk of overvoltage.

Q: What is the application scenario for SMD film capacitors?

A: It is suitable for PCB design with space limitation, such as consumer electronics and communication equipment.

Q: What is the production process of film capacitors?

A: Film metallization → winding/laminating → soldering → packaging → testing → aging.
