DC/DC converter (high voltage isolation capacitors)

FAQ

Q: How is the rated voltage selected?

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

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.

Q: How does frequency affect film capacitors?

A: Losses increase at high frequencies, so materials with good high frequency characteristics (such as PP or PPS) need to be selected.
