FAQ

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.

Q: What are the capacity error ranges?

A: Commonly ±5% (J), ±10% (K), ±20% (M), some precision capacitors up to ±1%.

Q: What is the operating temperature range of film capacitors?

A: -40°C to +105°C (conventional), special models can support -55°C to +125°C.
