The ETH1-460L_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 4-pair cabling plants
at 60 Watts. It exceeds the return loss requirements of
Gbit Ethernet.
This single component solution may be used in place of
two ETH1-230 parts, saving valuable board space.
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. Winding to
winding isolation is 1500 Vrms. Ambient temperature
range: –40°C to +85°C with 1 A current.
1. When ordering, please specify packaging code:
ETH1-460LD
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape.
Factory order only, not stocked (250 parts per full reel).
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter D instead.
