See How We Solve It →Our factory‑direct design eliminates the four pain points with a proven 5‑step process:
| Parameter | Typical Value | Tolerance | Standard |
|---|---|---|---|
| Leakage Inductance (Lleak) | 0.5 µH – 5 µH | ±3 % | IEC 60747‑2‑12 |
| DC Resistance (DCR) | 0.02 Ω – 0.15 Ω | ±5 % | MIL‑PRF‑5606 |
| Operating Frequency | 10 kHz – 10 MHz | – | EN 60721‑4‑1 |
| Temperature Range | ‑40 °C ~ +125 °C | – | UL 94 V‑0 |
From automotive EV chargers to medical imaging equipment, our low‑leakage chokes have delivered measurable gains:

Leakage inductance is the portion of magnetic flux that does not couple between the choke’s windings, creating a parasitic inductance that can resonate with circuit capacitance, raising EMI levels. Lower leakage means more predictable filtering and higher compliance with FCC/CE limits.
Yes. Our R&D team can adjust core material, winding geometry, and inter‑winding spacing to achieve any value between 0.1 µH and 10 µH with ±3 % tolerance.
Prototype: 2 weeks after design approval. Mass production: 4‑6 weeks, with 48‑hour air‑freight options for US customers.
Absolutely. We ship up to 10 free samples (including test reports) to the US within 5 business days. No obligation.
All shipments are accompanied by CE, FCC, RoHS, and a commercial invoice that meets US Customs and Border Protection (CBP) requirements. We also provide an ECCN classification for controlled items.
Order now and receive free 5‑piece sample kit plus a money‑back guarantee if the inductance tolerance exceeds ±3 %.
Offer valid until 30 June 2026 or until inventory depletes.
Michael Chen, Senior Purchasing Manager – Bosch
“The low‑leakage chokes cut our EMI audit cost by 37 % and the on‑time delivery helped us launch a new line three weeks early.”
Laura Patel, Operations Lead – Schneider Electric
“Xinchangda’s OEM service turned a 6‑month design cycle into a 3‑week prototype. The quality certificates made our FDA filing painless.”
David Kim, Technical Director – Qualcomm
“The sample kit proved the ±3 % tolerance claim. We’re now specifying Xinchangda as the sole supplier for all upcoming 5G base‑station filters.”
