This WE-LAN series LAN Transformer, part number 7490101120, is engineered for 1000BaseT applications compliant with IEEE 802.3ab standards. It offers a typical inductance of 350 µH at 100kHz and 8mA DC bias, with a nominal 1:1 turns ratio for both transmit (Tx) and receive (Rx) sides.
The transformer exhibits a maximum insertion loss of -1.0 dB at 1MHz and -18 dB at 60MHz, with a minimum return loss of -12 dB at 30MHz and -10 dB at 60MHz. Common mode rejection is a minimum of -30 dB at 100MHz, and crosstalk is -35 dB at 100MHz.
Constructed with a ferrite base material and Cu-Ni-Sn contact plating, the component has a UL94-V0 rated potting and wire insulation rated for 155°C. The operating temperature range is from 0°C to +70°C. Mechanical dimensions include a maximum length of 9.65 mm and a width of 12.7 ± 0.25 mm.
Electrical properties are verified with a Hipot test of 1500 Vrms for 1 minute. The transformer is suitable for use in networking equipment and other data communication systems requiring reliable signal integrity.
