Product Q&A

Q:What is a toroidal inductor used for?

It is mainly used for high-frequency filtering, energy storage, noise reduction and anti-interference in power inverters and switching power supplies.

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

Toroidal core has closed magnetic circuit, lower leakage flux, lower EMI, lower noise and higher efficiency than traditional inductors.

Q:Can you customize size and parameters?

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

Q:What causes inductor buzzing noise?

The main reason is loose coil vibration. We can do vacuum varnish dipping to eliminate noise completely.

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

DCR is DC resistance. Lower DCR means lower heat loss and higher inverter efficiency.
