Coilcraft, Inc. High Power PoE Plus Signal Path Magnetics HPX2126L HPX2126LD

The HPX2126L is a high-power PoE Plus signal path magnetic component integrating an isolation transformer and common mode choke in a single package, designed for Gigabit Ethernet applications. It has an open-circuit inductance of 850 µH at 100 kHz and 0 Adc, with a maximum DCR of 0.24 ohms per winding. The part provides 1500 Vrms isolation and can handle 1.9 A RMS current per secondary winding, causing a 20°C temperature rise from 25°C ambient. It supports a DC offset of 38 mA and can handle injected current up to 3.8 A. The component operates from -40°C to +85°C and meets IEEE 802.3af requirements for return loss, insertion loss, crosstalk, and common mode rejection. It is packaged in a tape-and-reel format compatible with EIA-481 embossed plastic tape, and features RoHS-compliant tin-silver-copper terminations. The package measures 18.29 mm x 14.22 mm x 10.80 mm max and includes a pin-1 indicator dot.
