Product Q&A

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

Blue-green cores use manganese-zinc ferrite for high permeability and superior high-frequency filtering. Black cores use nickel-zinc for ultra-high frequency & low current. Blue-green inductors excel in EMI suppression, with higher voltage resistance and saturation current, ideal for adapters and inverters.

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

We offer full customization for size, inductance, current, pin specs, and more to meet equipment needs and handle non-standard orders.

Q:What are the production cycle and MOQ requirements?

No MOQ for regular stock. 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 certificates, meeting global export standards and tailored to customer needs.

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

Our precision production ensures minimal tolerance and consistent parameters, reducing deviations, perfect for mass production.
