Why Your Current Common‑Mode Inductor Strategy Is Costly

Excessive EMI losses – Up to 25 % of total system inefficiency in industrial drives (source: IEC 61800‑3).
High unit price – Generic off‑the‑shelf parts can be 30‑50 % more expensive than a tailored design.
Unreliable quality – Inconsistent core material grading leads to ±15 % inductance variation, causing warranty claims.
Long lead‑times – Overseas suppliers often need 8‑12 weeks for standard stock, delaying production schedules.
Limited customization – Fixed dimensions prevent integration into compact power modules.

Result: Project overruns, lower ROI, and lost market competitiveness.

Frequently Asked Questions

What is the typical lead time for a custom common‑mode inductor prototype?

Our Fast‑Track service delivers a fully tested prototype within 48 hours after design approval, or within 30 days for larger batch sizes.

Can you handle low‑volume OEM orders for niche applications?

Yes. Minimum order quantity starts at 500 pcs, and we offer “Pay‑As‑You‑Go” tooling to keep costs low.

Do you provide design assistance for selecting core materials?

Our R&D team conducts a free EMI‑simulation and recommends the optimal core (Ferrite, Nanocrystalline, or Powdered Iron) based on frequency, temperature, and size constraints.

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

All products undergo in‑house testing and third‑party certification. Test reports are provided with every shipment.

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

We accept T/T 30 % deposit + 70 % before shipment, or L/C at sight. For qualified partners, we offer Net 30 after successful trial.

Do you provide after‑sales technical support?

Yes. Our 24/7 technical hotline and dedicated account manager ensure rapid issue resolution and design optimisation.
