FAQ

Q: How does the thickness of the metallized film affect performance?

A: The thinner the film, the higher the capacity, but the withstanding voltage may be reduced.

Q: How to ensure the voltage withstand performance of capacitors?

A: Through material selection, process control and 100% voltage withstand test.

Q: What is the purpose of aging test?

A: To screen for early failure products and ensure factory stability.

Q: What are the environmentally friendly processes?

A: Use of lead-free soldering, RoHS/REACH compliant materials.
