Product Q&A

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

The blue-green coated cores are manganese-zinc ferrite with high permeability and better high-frequency common-mode filtering performance. Black cores are mostly nickel-zinc for ultra-high frequency & low current. Blue-green inductors are widely used in adapters, chargers and inverters to suppress EMI, with higher voltage resistance and saturation current.

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

We support full customization. Adjustments in size, inductance, current, pin specifications, and other parameters are possible to meet equipment needs, handling non-standard orders.

Q:What are the production cycle and MOQ requirements?

No MOQ for regular stock with immediate delivery. Custom samples take 3-5 working days, bulk orders 7-10, and rush orders are accepted.

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

We provide comprehensive test reports and quality inspection certificates tailored to customer needs, meeting global export requirements.

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

Produced with precision, products in the same batch have minimal tolerance and consistent parameters, ensuring compatibility and reducing deviations, ideal for mass production.
