MIC24120-5101W-LF3 / MIC24121-5101W-LF3

Low Profile SMT RJ45 Connector with Integrated Magnetics

Quick Overview

The MIC24120-5101W-LF3 and MIC24121-5101W-LF3 are low-profile, surface-mount RJ45 connectors with integrated magnetics, designed for 10/100BASE-T Ethernet applications. By integrating the transformer, impedance resistor, and high-voltage capacitor into a compact RJ45 footprint, these models significantly reduce EMI radiation, save PCB space, and enhance design efficiency.
