ETH1-230 High Power

PoE+ PoE++ Signal Path Magnetics

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 802.3.bt 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
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

Notes

When ordering, please specify packaging code: e.g. ETH1-230LD
1500 Vrms winding to winding isolation.

Termination:

RoHS-compliant. 260°C compatible. Tin-silver-copper over tin over nickel over phos bronze terminations.

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (400 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
