Product Q&A

Q:What's the difference between blue-green toroidal inductors and ordinary black toroidal inductors?

Blue-green cores are manganese-zinc ferrite with high permeability for superior high-frequency filtering. Black cores, mostly nickel-zinc, suit ultra-high frequency & low current. Blue-green inductors, widely used in adapters, chargers, and inverters, offer high voltage resistance and saturation current.

Q:Can non-standard sizes and parameters be customized?

We offer full customization, including size, inductance, current, and pin specifications, accommodating non-standard orders.

Q:What are the production cycle and MOQ requirements?

No MOQ for stock; immediate delivery. Custom samples: 3-5 days, bulk: 7-10 days. Rush orders accepted.

Q:Does the product meet export environmental standards? Can you provide certification reports?

We offer detailed test reports and quality certificates, compliant with global export standards.

Q:How about parameter consistency for bulk purchases? Will there be abnormal operation?

Precision production ensures minimal tolerance and consistent parameters within batches, reducing deviations, ideal for mass production.
