The Pain Points You Face Today

High component cost – Generic chokes cost up to 30% more than a bulk‑produced OEM part.
Unreliable EMI suppression – Out‑of‑spec parts cause > 5 % failure rates in compliance testing.
Long lead times – Overseas suppliers often need 8‑12 weeks, delaying product launches.
Regulatory uncertainty – Lack of CE/FCC/GS certification leads to costly re‑engineering.
Limited customization – One‑size‑fits‑all designs cannot meet specific current‑rating or footprint requirements.

Result: Missed market windows, inflated OPEX, and reduced competitiveness.

Frequently Asked Questions

1. How long does a custom OEM order take?

Standard designs ship in 7 days from order confirmation. Custom winding or footprint modifications require 15‑20 days, with a 48‑hour engineering sample for verification.

2. Can you meet FCC Part 15 Class B requirements?

Yes. All our chokes are pre‑tested and carry FCC certification. Test reports are provided with every shipment.

3. What are the minimum order quantities (MOQs)?

MOQs start at 5 k pieces for standard part numbers. For custom designs, the MOQ is 2 k pieces, but we can discuss lower volumes for prototyping.

4. Do you offer free samples?

We provide up to 10 pcs of engineering samples at no charge (shipping paid by buyer). Samples are fully functional and carry the same certifications as production units.

5. What logistics options are available for US buyers?

Air freight (2‑3 days), DHL Express, or sea freight (30‑45 days). We handle customs documentation and can arrange DDP (Delivered Duty Paid) for hassle‑free import.

6. How is after‑sales support handled?

Dedicated technical account manager, 24 / 7 email support, and a 12‑month warranty covering material and workmanship.
