Why Your Current EMI Strategy Is Losing Money
Over‑priced choke modules: Average US market price is 45% higher than OEM baseline.
Inconsistent quality: 22% of field failures trace back to tolerance drift in common‑mode chokes.
Long lead times: Typical 6‑8 week delivery stalls production lines.
Regulatory uncertainty: Non‑compliant parts risk FCC/CE penalties up to $150k.
Result: Delayed shipments, warranty claims, and a hit to your ROI.

Testimonials:
John M., Procurement Manager, Siemens: “Switching to Xinchangda cut our choke cost by 38% and lead time from 6 weeks to 9 days. No more EMI re‑work.”
Laura K., Technical Director, GE Healthcare: “Their OEM design team helped us meet FDA‑EMC standards on the first try – a 0% failure rate in production.”
Mike T., Operations Lead, Tesla Energy: “Fast‑track samples arrived in 24 h, enabling our prototype schedule to stay on track.”
How do I determine the required inductance for my application?
Start with the target common‑mode noise frequency (typically 10 kHz‑1 MHz). Use the formula L = V / (2πfI) where V is the allowable voltage ripple, f is the noise frequency, and I is the line current. Our engineers can run a quick simulation for you.
Can Xinchangda provide custom core materials?
Yes. We stock ferrite, powdered iron, and nanocrystalline cores. OEM/ODM projects can specify permeability, saturation flux density, and temperature rating.
What is the minimum order quantity (MOQ) for standard chokes?
Our standard catalog items start at 500 pcs. For larger batches we offer volume discounts and free freight to the US mainland.
How long does shipping take to the United States?
Express (DHL/UPS) – 3‑5 business days; Air freight – 7‑10 days; Sea freight – 20‑25 days. All shipments are tracked.
Do you offer after‑sales testing or warranty support?
Every batch undergoes 100% electrical testing. We provide a 12‑month warranty and on‑site failure analysis if needed.
