It is a right-angle, through-hole mounted connector with a shielded stainless steel shell and integrated EMI fingers that provide a low-impedance ground path to the chassis panel. The through-hole solder termination requires plated through-holes in the PCB footprint; the board lock adds two additional plated holes for mechanical retention. The shielded shell with EMI fingers means the PCB layout should include a ground plane connection to the shell pins and a chassis ground pad where the fingers contact the panel cutout — this is critical for meeting FCC/EMC radiated emissions limits on a 1000 Base-T port. ## Signal Integrity for 1000 Base-T Rated for 10/100/1000 Base-T and AutoMDIX, this jack is specified for the 4 differential pair signaling used in Gigabit Ethernet over twisted pair. The shielded construction and EMI fingers help contain common-mode noise and reduce crosstalk between the pairs within the connector. The part is packaged in trays, which is standard for through-hole RJ45 jacks in production volumes.","metaTitle":"Molex 85793 0857931020 RJ45 Jack, 1 Port, Shielded","metaDescription":"Molex 0857931020 RJ45 jack, 1 port, right-angle, through-hole, shielded with EMI finger, board lock, 30.0µin gold, 0°C~70°C.
