Product Q&A

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

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

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

Full customization supported. Size, inductance, current, pin specs, and other parameters can be adjusted to meet equipment needs, handling non-standard orders.

Q:What are the production cycle and MOQ requirements?

No MOQ for regular 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 provide comprehensive test reports and quality inspection certificates for customer needs, meeting global export requirements.

Q:How about parameter consistency for bulk purchases? Abnormal operations?

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