Why Your Current Inductor Strategy Fails

Excessive price spikes: Traditional suppliers charge up to 30% more for low‑volume orders.
Unreliable performance: High‑current designs often suffer from core saturation, causing 15‑25% efficiency loss.
Long lead‑times: Overseas factories average 45‑60 days, jeopardizing production schedules.
Limited customization: Off‑the‑shelf parts cannot meet specific inductance, current, or size requirements.
Compliance risk: Missing CE, RoHS, or UL certifications can halt shipments to the US market.

Result: Project delays, increased OPEX, and lost market share.

Frequently Asked Questions

What is the minimum order quantity for custom high‑current ferrite toroid inductors?

Our standard MOQ is 5,000 pieces per design. For bulk projects (≥ 50,000 pcs) we can reduce tooling costs and offer additional discounts.

Can you provide OEM/ODM design services for specific inductance and current ratings?

Yes. Our 10 R&D engineers work with you from concept to final testing, delivering fully qualified parts that meet your datasheet.

What are the payment terms for first‑time overseas buyers?

We accept T/T (30 % advance, 70 % before shipment) or L/C at sight. For trusted partners, net‑30 after delivery is available.

How do you ensure compliance with US regulations (UL, FCC, RoHS) for export?

All units undergo third‑party testing and receive a full test report (TR, CoC) before shipping. Certificates are uploaded to our portal for your audit.
