The
ETH1-230L_1 is developed for high power PoE ap-
plications in support of the goals of the IEEE 802.3at-
2009 standard.This module is designed for 2-pair cabling
plants at 30 Watts and two modules may be used for
4-pair cabling in 60 Watt applications. It exceeds the
return loss requirements of Gbit Ethernet.
L vs Offset Current
It has a minimum open-circuit inductance of 350 H at an
offset current of 35 mA at 25°C ambient temperature, and
can handle 22.5 mA minimum dc offset at 85°C. Typical
temperature rise from 25°C ambient is 7°C with 800 mA
and 10°C with 1000 mA dc current applied. Winding to
winding isolation is 1500 Vrms. Ambient temperature
range: –40°C to +85°C with 1 A current.
