Product Overview
The HX1178NLMT is a 10/100M Single Port Transformer Module designed for Ethernet applications. It is compatible with various 10/100 Base-TX transceivers requiring a 1:1 transmit and receive turns ratio. This module complies with the IEEE 802.3ab standard, featuring baseline wander compensation with 350H OCL when biased at 8mA. Its low-profile surface mount packaging is suitable for Hi-Temp Reflow Processes. The single-channel interface incorporates Common Mode Chokes (CMCs) tuned to enhance EMC system performance. It operates within a temperature range of 0 to +70 and can be stored between -25 to +125.
