poe plus magnetics C eth1-460 document 1008-1 document 1008-1 revised 10/09/12 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 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. winding to winding isolation is 1500 vrms. ambient temperature range: C40c to +85c with 1 a current. 1. when ordering, please specify packaging code: eth1-460l d 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. dimensions are in inches mm core material ferrite terminations rohs compliant tin-silver-copper over tin over nickel over phos bronze weight 3.6 g ambient temperature C40c to +85c storage temperature component: C40c to +85c. tape and reel packaging: C40c to +80c resistance to soldering heat max three 40 second refows at +260c, parts cooled to room temperature between cycles moisture sensitivity level (msl) 1 (unlimited foor life at <30c / 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 250/13 reel; plastic tape: 32 mm wide, 0.5 mm thick, 24 mm pocket spacing, 10.6 mm pocket depth pcb washing only pure water or alcohol recommended us uk t aiwan china singapore +1-847-639-6400 sales@coilcraft.com +44-1236-730595 sales@coilcraft-eur ope.com +886-2-2264 3646 sales@coilcraft.com.tw +86-21-6218 8074 sales@coilcraft.com.cn + 65-6484 8412 sales@coilcraft.com.sg ? coilcraft inc. 2012 this pr oduct may not be used in medical or high risk applications without prior coilcraft appr oval. specification subject to change without notice. please check out web site for latest infor mation.
