FAQ

Q: What are the levels of capacity error range?

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.

Q: How does frequency affect film capacitors?

A: Losses increase at high frequencies, so it is necessary to choose materials with good high frequency characteristics (e.g. PP or PPS).

Q: What is the angular tangent of loss (tanδ)?

A: The smaller the tangent of the loss angle, the higher the efficiency of the capacitor and the lower the heat generation.

Q: What is the application of film capacitors in new energy field?

A: Used in photovoltaic inverters, wind power converters, electric vehicle motor drives, etc.
