Each port presents the standard 8-position, 8-contact layout used in twisted-pair Ethernet, and the entire assembly is shielded with an EMI finger that grounds through the panel cutout. The housing is polyamide (nylon) with a board guide to aid alignment during through-hole soldering. This is a ganged I/O connector meant for network interface cards, industrial switches, or any equipment where four Ethernet ports need to live side-by-side on a single PCB footprint. The Cat5 rating means this jack is characterized for 100 MHz operation — sufficient for 10BASE-T, 100BASE-TX, and 1000BASE-T (Gigabit Ethernet) over four twisted pairs. It does not carry a Cat5e or Cat6 rating, so the NEXT and return-loss margins are tighter at higher frequencies. For a standard office or industrial control network running 1000BASE-T, the Cat5 ceiling is adequate; if the design targets 10GBASE-T or PoE++ at full bandwidth, a Cat6A-rated jack would be the safer call. The shield and EMI finger help contain radiated emissions at the I/O boundary, which is the main reason to pick a shielded jack over an unshielded one in the same footprint. It ships in tray packaging, which is standard for a ganged through-hole part of this size — not optimized for tape-fed pick-and-place, but workable for hand-load or tube-fed selective solder lines.","metaTitle":"TE Connectivity 5406281-3, 8p8c RJ45 Jack, Cat5","metaDescription":"TE 5406281-3 modular jack, 8p8c (RJ45), Cat5 rated, right-angle through-hole, shielded with EMI finger, 4-port, -40 to 85°C.
