The Real Pain Points of Purchasing Managers

Escalating component costs – Prices have risen 12 % YoY, squeezing margins.
Unreliable quality – Inconsistent inductance and high loss rates cause product failures.
Long lead times – Traditional suppliers need 6‑8 weeks, delaying launches.
Limited customization – OEM/ODM options are often “one‑size‑fits‑all”.
Compliance headaches – Missing CE, RoHS or FCC certifications stalls import clearance.

According to a 2025 IEC survey, **37 %** of B2B buyers cite “inconsistent specifications” as the top reason for switching suppliers.

Frequently Asked Questions

What is the minimum order quantity (MOQ) for the 22uh choke?

Our standard MOQ is 5,000 pieces. For rapid‑prototype needs, we can supply as low as 500 pieces with a short lead‑time.

Can you customize the inductance tolerance or form factor?

Yes. Our R&D team offers tolerance options from ±5 % to ±1 % and can mill custom dimensions to fit PCB footprints.

What are the payment terms for first‑time buyers?

We accept T/T (30 % deposit, 70 % before shipment) or L/C at sight. For qualified partners, net‑30 days is available.

How do you ensure compliance with US import regulations?

All units carry CE, FCC, and RoHS markings. We provide full test reports and can arrange third‑party inspection upon request.
