Product Overview

This single-port transformer module is designed for 10/100Mbps Ethernet applications, compatible with various 10/100 Base-TX transceivers requiring a 1:1 transmit and receive turns ratio. It complies with the IEEE 802.3ab standard, including baseline wander compensation with 350H OCL at 8mA DC bias. The low-profile, surface mount packaging is suitable for Hi-Temp Reflow processes. This module features a single channel interface with Common Mode Chokes (CMCs) tuned to enhance EMC system performance. It operates within a temperature range of 0 to +70, with a storage temperature range of -25 to +125.
