Product Description
Product Overview
The TB12140111 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 802.3af standard, including baseline wander compensation. It features a low-profile Surface Mount Packaging suitable for Hi-Temp Reflow Processes and a single channel interface for 10/100Mbps Ethernet. The Common Mode Chokes (CMCs) are tuned to enhance EMC system performance.
