Single-Port Shielded RJ45 for 10/100 Base-T
The TE Connectivity 2301994-2 is a single-port RJ45 jack designed for 10/100 Base-T Ethernet applications. It is a right-angle, through-hole component with a shielded body and an integrated EMI finger for noise suppression. The connector includes a board lock for secure PCB retention during soldering and in service, and it carries a green-yellow LED for link/activity indication. This jack is built for 4 cores per jack, matching the 4-pair wiring of 10/100 Base-T.
The tab direction is up, which determines the latch orientation on the mating plug. The single-row, single-port design keeps the PCB footprint compact. The through-hole termination provides a robust mechanical connection, preferred over SMT in high-vibration environments or where the connector sees frequent mating cycles.
The brass shield with an integrated EMI finger provides a low-impedance path to chassis ground, reducing radiated emissions and improving immunity in electrically noisy environments. This is essential for passing FCC/EMC pre-compliance in industrial or telecom equipment. The shielding is specified for 10/100 Base-T, where signal integrity at 100 MHz is a concern.
