Product Q&A

Q:What is a toroidal inductor used for?

Primarily used for high-frequency filtering, energy storage, noise reduction, and interference mitigation in power inverters and switching power supplies.

Q:Why choose toroidal inductor instead of EE or drum inductor?

Toroidal cores offer closed magnetic circuits, reduced leakage flux, EMI, noise, and enhanced efficiency over traditional inductors.

Q:Can you customize size and parameters?

Yes, full OEM/ODM customization includes inductance, current, size, wire diameter, and mounting type.

Q:What causes inductor buzzing noise?

Loose coil vibration is the main cause. Vacuum varnish dipping can fully eliminate noise.

Q:What is DCR? Why low DCR is important?

DCR stands for DC resistance. Lower DCR equates to reduced heat loss and improved inverter efficiency.
