FAQ

Q: How to select capacitors for high humidity environment?

A: Choose moisture-proof package (e.g. epoxy resin potting) or moisture-resistant material (e.g. PPS).

Q: How to select capacitors for scenes that need to withstand high-frequency pulses?

A: Give preference to metallized polypropylene capacitors to support high dv/dt and pulse current.

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

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

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

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