Product Q&A
Q:What is a toroidal inductor used for?
A:
Primarily 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, reduced leakage flux, lower EMI, less noise, and higher efficiency.
Q:Can you customize size and parameters?
A:
Yes, we provide full OEM/ODM customization, including inductance, current, size, wire diameter, and mounting type.
Q:What causes inductor buzzing noise?
A:
Loose coil vibration is the main cause. We use vacuum varnish dipping to 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.
