“PoE Plus” Magnetics
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.
It has a minimum open-circuit inductance of 350 µH 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 to one center
tap of each isolation transformer. Winding to winding isola-
tion is 1500 Vrms. Ambient temperature range: –40°C to
+85°C with 1 A current.
