Tape and reel packaging: –40°C to +80°C Resistance to soldering heat Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C / 85% relative humidity) Failures in Time (FIT) / Mean Time Between Failures (MTBF) 60 per billion hours / 16,666,667 hours, calculated per Telcordia SR-332 Packaging 400/13″ reel; Plastic tape: 32 mm wide, 0.5 mm thick, PCB washing Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. See Doc787_PCB_Washing.pdf. “PoE Plus” Magnetics Document 538-1 Document 538-1 Revised 11/02/11 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. 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). 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.
