Document 538-1 30 W / 60 W PoE+ / PoE++ Magnetics for signal path 1 AEC The ETH1-230L is developed to meet the IEEE 802.3at- + Q200 85C 2009 and IEEE 802.3.bt Type 3 standard for PoE+ and PoE++ applications. This module is designed for 2-pair cabling plants at 30 / 60 Watts and two modules may be used for 4-pair cabling in 60 / 120 Watt applications. It exceeds the return loss requirements of Gbit Ethernet. It has a minimum open-circuit inductance of 350 H at an offset current of 35 mA at 25C ambient temperature, and can handle 22.5 mA minimum dc offset at 85C. Typical temperature rise from 25C ambient is 7C with 800 mA and 10C 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: 40C to +85C with 1 A current. Request free evaluation samples by contacting Coilcraft or visiting www.coilcraft.com. 1. When ordering, please specify packaging code: ETH1-230LD 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). TX+ 6 B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for 9 TX+ multiple packaging codes. When ordering, simply change 10 the last letter of your part number from B to D.
