Modular Jack for Shielded Ethernet — 8P8C Vertical Mount
It carries a Cat3 rating, which means it is specified for voice and 10BASE-T applications up to 16 MHz — not for 100BASE-TX or higher-speed Ethernet that requires Cat5e or better. The shielded shell with an EMI finger provides a low-impedance path to chassis ground, making this jack suited for industrial panels or telecom equipment where radiated emissions need to be contained. This is a single-port, single-row design with user-selectable tab direction — the tab-up or tab-down orientation is set by the PCB layout, not the connector itself.
The Cat3 rating is the key performance spec: it certifies the jack for frequencies up to 16 MHz, covering voice (POTS) and 10BASE-T Ethernet. It is not rated for 100BASE-TX (100 MHz) or Gigabit Ethernet — those require a Cat5e or Cat6 jack. The shielded construction does not upgrade the category rating — shielding reduces EMI ingress/egress but does not change the transmission-line performance that defines Cat3 vs Cat5e. For a shielded Cat5e jack, look to TE's other modular jack series with a Cat5e or Cat6 rating.
