“Switching to Xinchangda’s optimized common mode coil cut our EMI‑related re‑work by 45% and accelerated our time‑to‑market by 3 weeks.” – John Liu, Procurement Manager, GreenPower Solutions
All products are manufactured under ISO 9001:2015 quality management and hold CE, FCC, RoHS, and CB certifications. Our factory complies with GS, VDE, and SAA standards, ensuring hassle‑free import to the U.S., EU, and Australia.
A common mode coil suppresses differential currents that generate electromagnetic interference (EMI). In energy storage systems, uncontrolled EMI can cause inverter trips, safety‑system shutdowns, and non‑compliance with IEC/UL standards.
Yes. Our 10 R&D engineers can co‑design windings, core materials, and form factors to meet any inductance (0.5‑5 µH) and current rating up to 30 A.
We accept T/T 30% deposit, 70% balance before shipment, or LC at sight. For qualified accounts, we offer Net 30 after delivery.

Our semi‑automated lines can finish a 5k‑unit batch in 14 days after artwork approval, with FOB Shenzhen shipping.
All coils carry a 12‑month warranty. We also offer on‑site testing support and a 30‑day free‑return policy for defective units.
Order a 10‑piece sample kit within the next 7 days and we’ll cover shipping. If the coil does not meet your specs, we’ll refund 100% of the sample cost.
