Product Q&A
Q:What is a toroidal inductor used for?
A:
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?
A:
Toroidal core offers closed magnetic circuit, lower leakage flux, EMI, noise, and higher efficiency than traditional inductors.
Q:Can you customize size and parameters?
A:
Yes, full OEM/ODM customization includes inductance, current, size, wire diameter, and mounting type.
Q:What causes inductor buzzing noise?
A:
Loose coil vibration is the main cause. Vacuum varnish dipping can eliminate noise completely.
Q:What is DCR? Why low DCR is important?
A:
DCR is DC resistance. Lower DCR means reduced heat loss and enhanced inverter efficiency.
