Xinchangda’s power common mode choke combines a 14‑year R&D legacy with 14 fully‑automated production lines, delivering 450 k units/month of magnetic components that meet CE, FCC, RoHS, ISO 9001, and VDE standards.
Imagine a production line halted because a single choke fails to meet EMI standards—resulting in lost revenue, warranty claims, and brand damage.
See How We Solve It →| Parameter | Typical Range | Standard |
|---|---|---|
| Inductance (L) | 0.5 µH – 10 µH | ±5 % |
| Rated Current (IRMS) | 5 A – 100 A | ±10 % |
| Saturation Current (Isat) | 1.2 × IRMS | ±8 % |
| DC Resistance (DCR) | ≤30 mΩ | ≤5 % |
| Operating Temp. | ‑40 °C – +125 °C | RoHS‑compliant |
| Package Options | Through‑hole, Surface‑mount, Custom PCB‑mount | IPC‑2221 |
A power common mode choke (CM‑choke) suppresses common‑mode noise on DC‑bus lines. It is essential in industrial power supplies, medical equipment, and renewable‑energy inverters where EMI can cause functional failures or regulatory non‑compliance.
Yes. Our R&D team can deliver custom values from 0.5 µH to 10 µH and current ratings from 5 A up to 100 A, with tolerance control better than ±5 %.
Standard production is 14 days after design approval. Expedited shipping (air freight) can deliver within 7 days for stocked cores.
All units ship with a full test report, CE Declaration of Conformity, FCC ID, and RoHS compliance certificate.
We accept T/T, L/C, and PayPal for samples. For bulk orders, we offer 30 % advance, 70 % before shipment, with DDP or FOB options via DHL, UPS, or ocean freight.
Stock is limited. Secure your power common mode choke today and enjoy risk‑free testing with our money‑back guarantee.
