Compliance & Reliability of 10/100BASE-T SMT RJ45

  • Designed in accordance with IEEE 802.3 Fast Ethernet requirements
  • Suitable for lead-free SMT assembly processes
  • Industrial-grade temperature performance
  • Proven solution used in Ethernet magnetic modules and magjack designs

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
