Product Description

Product Overview

The 11FB-05NL is a single-port transformer module designed for 10/100 Mbps 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 802.3at standard, offering baseline wander compensation and a 720mA current capability per POE port, making it suitable for both End-span and Mid-span POE+ applications. Its low-profile surface mount packaging is designed for Hi-Temp Reflow processes, and it features Common Mode Chokes (CMCs) tuned to enhance EMC system performance.
