Belfuse SI-51005-F Magjacks RJ45 Connector With LEDs LPJG17332AWNL
SI‑51005‑F is a single-port RJ45 Jack with integrated magnetics, shielded EMI shell, gold‑plated contacts, and right‑angle through‑hole mount — ideal for Gigabit Ethernet, industrial switches, routers, media converters, and embedded network devices requiring compact design and reliable EMI performance.
Overview of Gigabit Magjack
The SI-51005-F is a high-performance 1×1 RJ45 Integrated Connector Module (ICM) designed for 10/100/1000Base-T Ethernet applications.
It integrates the RJ45 interface, magnetics (transformer, chokes), EMI components, LEDs, and shielding into one compact module, significantly reducing PCB layout complexity and improving signal integrity.
This connector is ideal for network devices requiring high reliability, strong EMI suppression, and efficient PCB design, including switches, routers, industrial controllers, IoT gateways, and embedded Ethernet systems.
