The Cat3 rating limits the usable frequency range to 16 MHz, which means this jack is suited for analog telephony, basic ISDN, and low-speed serial data links rather than modern Ethernet or PoE applications. The vertical SMT orientation places the plug entry perpendicular to the PCB, a layout choice for edge-mounted or low-profile front-panel designs where the cable exits straight up from the board. ## Contact Plating and Mechanical Retention This plating grade supports several hundred mating cycles in field-service environments where connectors are reconnected during equipment maintenance. There are no through-hole posts — all mechanical hold comes from the SMT solder joints and the board guide. ## Shielding and EMI Considerations This jack is unshielded — there is no metal shell or grounding tabs to bleed common-mode noise or shield the contacts from external interference. In a metal enclosure with a grounded front panel, the chassis itself provides the EMI containment; in a plastic enclosure the jack offers no RF suppression. If the application requires conducted or radiated emissions control, a shielded equivalent from the same TE base product number family (1734858) would be the correct choice — the unshielded variant is for cost-sensitive or low-noise internal wiring where the surrounding system already manages the interference budget.","metaTitle":"TE 1-1734858-3 Modular Jack, 6P6C Vertical Unshielded","metaDescription":"TE Connectivity 1-1734858-3 Cat3 modular jack, 6p6c (RJ11/RJ12/RJ14/RJ25), vertical SMT, unshielded, 30µ\" gold contacts.
