FAQ

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.

Q: What are the advantages and disadvantages of film capacitors?

A: Advantages: high voltage resistance, low loss, high reliability; Disadvantages: relatively large size, limited capacity range.

Q: What are the common types of film capacitors?

A: Such as Box, Radial, SMD and Power film capacitors.

Q: How to choose the rated voltage?

A: It needs to be higher than 1.5 times the maximum operating voltage of the circuit, and temperature derating should be considered.
