7498111120A

The 7498111120A is a modular connector jack with integrated magnetics from Würth Elektronik, part of the WE-RJ45LAN series. It is designed for 10/100/1000 Base-T Ethernet applications with AutoMDIX capability. The connector features a single RJ45 port with 8 cores, shielded with EMI finger, and a 90° right angle orientation with tab up. It supports board edge and surface mount mounting with solder termination. The contact finish is gold, and the housing is made of thermoplastic UL 94V-0. The operating temperature range is -40°C to 85°C. Electrical specifications include a minimum inductance of 350 µH at 100kHz/100mV with 8mA DC bias, 1:1 turns ratio for Tx and Rx, insertion loss of -1.0 dB max from 1-100MHz, and return loss of -18 dB min at 1-30MHz. Common mode rejection ratio is -30 dB min at 1-30MHz and -20 dB min at 30-100MHz. Crosstalk is -37 dB min at 1-30MHz. Hipot test voltage is 2250 Vdc for 1 minute. The LED is yellow-green with forward voltage 1.8-2.5V at 20mA. The package is an RJ45 jack with magnetics, board edge/surface mount, solder termination. This component is suitable for high-speed Ethernet applications requiring integrated magnetics for signal isolation and EMI protection.
