ETH1-460 PoE

Signal Path Transformer

RoHS compliant
  • Developed to meet the IEEE 802.3at-2009 and IEEE Type 4 standard for PoE+ and PoE++ applications
  • Designed for 4P cabling plants at 60 / 120 Watts. For 2P cabling plants see ETH1-230.
  • Exceeds the return loss requirements of Gbit Ethernet
  • 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
