Cut energy loss, boost reliability, and lower total cost of ownership for your power systems.
When an inductor fails to meet the required DC resistance (DCR), current ripple, or thermal rating, the consequences ripple through your entire production line:
Imagine a 500 kW industrial inverter that loses 3% efficiency—over a year, that’s more than 150 MWh wasted, equivalent to $15,000 in electricity costs for a US plant.
| Parameter | Typical Range | Unit | Compliance |
|---|---|---|---|
| Inductance | 0.1 – 200 | mH | IEC 60217 |
| DC Resistance (DCR) | 0.01 – 5 | Ω | UL 94V‑0 |
| Current Rating | 5 – 500 | A | IEC 60784‑2‑2 |
| Operating Temp. | ‑40 – +125 | °C | RoHS, REACH |
| Packaging | Reel, Tray, Bulk | - | ISO 13485 (Medical) |
Case 1 – Solar Inverter Manufacturer (USA): Re‑engineered a 5 kW inverter’s dc filter network, reducing DCR by 28% and boosting overall efficiency by 1.5% (≈ $12 k annual savings).
Case 2 – Medical Imaging Equipment (Europe): Delivered a custom high‑frequency dc inductor with < 0.02 Ω DCR, meeting IEC 60601‑1 standards and passing FDA 510(k) clearance.
We can deliver a functional prototype within 7 business days after final design approval, including material sourcing and first‑article testing.
Yes. Our engineering team designs to the exact standard you require and provides full test reports and certificates on request.
Absolutely. Our semi‑automated lines can handle batches as small as 500 units with the same quality controls as high‑volume runs.
We accept T/T 30 % deposit + 70 % before shipment, or L/C at sight. For qualified accounts, Net 30 terms are available after the first order.
All inductors come with a 12‑month warranty covering material defects. Our technical support desk is available 24 × 5 via email, phone, and WhatsApp.
Limited‑time offer: Free engineering sample (up to 10 pcs) for orders placed before 30 April 2026. Stock is limited to 5,000 pcs per month.
Emily Carter, Senior Engineer – SolarTech USA
"The custom dc inductor we received met the 0.015 Ω DCR spec on the first try. Production ramp‑up was seamless, and we saved $18 k in the first quarter."
Michael Tan, Procurement Lead – MedEquip Europe
"Xinchangda’s ISO‑13485 certification gave us confidence for FDA 510(k) submission. Delivery was on time, and the parts passed all validation tests."
Sarah Liu, Operations Manager – AutoDrive Corp (USA)
"After switching to Xinchangda’s high‑current dc inductors, our motor‑controller failure rate dropped from 4.2% to 0.9% within two months."
