Why Your Current PFC Choke Is Holding Back ROI

High Harmonic Distortion – Increases grid penalties by up to 15%.
Oversized Footprint – Adds 30 % more PCB area, raising manufacturing costs.
Long Lead Times – 8‑12 weeks from most Asian suppliers, delaying product launches.
Inconsistent Quality – Failure rates above 2 % cause warranty spikes.
Regulatory Non‑Compliance – Missing CE/FCC marks leads to costly redesigns.

A recent survey of 200 U.S. OEMs showed 37 % of projects missed schedule due to choke‑related issues. Discover how Xinchangda solves these problems.

Frequently Asked Questions

How long does a custom PFC choke design take from concept to delivery?

Standard OEM designs are ready in 4 weeks; complex ODM projects typically require 6‑8 weeks, including prototype testing.

Can you meet UL 60950‑1 and IEC 61000‑4‑3 compliance?

Yes. All our PFC chokes are pre‑tested to UL, CE, FCC, and IEC standards. Test reports are provided on request.

Do you offer low‑volume production for pilot runs?

Minimum order is 500 pcs for standard sizes; for prototypes we can produce as few as 50 units with the same quality level.

What payment terms are accepted for overseas buyers?

We accept T/T, L/C, PayPal, and major credit cards. For first‑time customers, a 30 % deposit is standard.

Is after‑sales technical support included?

Yes. Our R&D engineers provide 24/7 email support and a dedicated account manager for the product’s lifecycle.
