7498011122 SMT RJ45 Connector With 10/100BASE-T Magnetics
7498011122 (WE-RJ45LAN): 1-port SMT 10/100BASE-T RJ45 jack with integrated LAN transformer, 350µH OCL, Auto-MDIX, −40 to +85°C.
Why Choose 7498011122 RJ45 With Magnetics?
The 7498011122 (WE-RJ45LAN) is a 1-port, surface-mount 10/100BASE-T RJ45 connector with integrated LAN transformer (magnetic + connector). It is Auto-MDIX capable, optimized for SMT/reflow assembly, rated for industrial temperatures, and built with ferrite magnetics and robust shielding for reliable Ethernet links on embedded, industrial and communications boards.
- Integrated magnetics + RJ45 in one SMT package — reduces BOM, board area and assembly complexity.
- Engineered for 10/100BASE-T with PHY-friendly 1:1 turns ratio and high OCL for stable signal integrity.
- Industrial temperature range (-40 °C to +85 °C) and high isolation for reliable field operation.
- Auto-MDIX support reduces cabling errors in deployments.
