PoE+ / PoE++ Magnetics
for 30 / 60 Watt Signal Path

For higher power applications, consider the Coilcraft HPX2126L Isolation Transformer and HPF2187L Common Mode Choke. DETAILS

  • Developed to meet the IEEE 802.3at-2009 and IEEE Type 3 standard for PoE+ and PoE++ applications
  • Designed for 2P cabling plants at 30 / 60 Watts. For 4P cabling plants consider the ETH1-460.
  • Exceeds the return loss requirements of Gbit Ethernet
  • 1500 Vrms winding to winding isolation
  • 350 µH minimum at 35 mA offset current at 25°C
  • Can handle 22.5 mA minimum dc offset at 85°C.
  • Typical temperature rise: 7°C with 800 mA; 10°C with 1000 mA dc current applied to one center tap of each isolation transformer
  • Ambient temperature range: −40°C to +85°C with 1 A dc current applied
  • RoHS-compliant. 260°C compatible. Tin-silver-copper over tin over nickel over phos bronze terminations
