749013011 10/100BASE-TX Power Over Ethernet Transformer SMT Module

Introduction:

The WE-LAN 749013011 is a compact surface-mount (SMT) LAN transformer specifically designed for 10/100BASE-T Ethernet applications. Supporting Power over Ethernet (PoE), it ensures both data transmission and power delivery through a single Ethernet cable. This component provides excellent signal integrity, electrical isolation, and complies with IEEE 802.3 and IEEE 802.3af standards, making it ideal for industrial, commercial, and network communication devices.

The 749013011 PoE transformer plays a critical role in Ethernet interfaces. It provides:

Electrical isolation between PHY and network lines.
Low insertion loss and high common-mode rejection, ensuring stable data transmission.
PoE compatibility, supporting current up to 350 mA per center tap.
RoHS and REACH compliance, ensuring environmentally safe design.

This LAN transformer meets the reliability and performance demands of modern Ethernet systems, including those operating in harsh industrial environments.
