Design Notes for SMT RJ45 Connector Applications

 

MIC24121-5308W-LF3 integrates Ethernet magnetics directly inside the RJ45 connector housing, allowing designers to eliminate discrete transformer components.


This improves signal integrity, reduces EMI, and simplifies PCB routing in high-density layouts.
The high isolation voltage and strong common-mode rejection make it suitable for industrial Ethernet environments.

 

Typical Applications

 

  1. SMT RJ45 connectors for Ethernet ports
  2. Fast Ethernet LAN interfaces (10/100 Mbps)
  3. Embedded systems and industrial controllers
  4. Network switches, routers, gateways
  5. IoT devices and communication equipment
  6. Consumer and industrial Ethernet products
