Product Description
Product Overview
The TB1212011 is a single-port 10/100M POE+ 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 and complies with the IEEE 802.3af standard, including baseline wander compensation. This module features a low-profile surface mount packaging suitable for Hi-Temp Reflow Processes and is designed for both End-span and Mid-span POE+ applications, offering a 720mA current capability per POE port. Its single-channel interface is enhanced with tuned Common Mode Chokes (CMCs) for improved EMC system performance.
