The shielded shell and board guide features help manage EMI and simplify alignment during PCB assembly. The housing is molded from PCT (Polycyclohexylenedimethylene Terephthalate), a high-temperature thermoplastic that withstands lead-free reflow profiles without distortion. ## Shielded vs Unshielded — Why It Matters Here The 5557786-1 is a shielded jack. The practical difference from an unshielded version (like a standard plastic-body RJ45) is that the metal shell provides a low-impedance path to ground for coupled interference. In a Cat3 signal environment — typically voice or 10BASE-T — the noise margin is already tight, so the shielding helps maintain signal integrity over longer cable runs or in electrically noisy racks. The trade-off is that the shield must be properly grounded through the PCB; a floating shield can act as an antenna and worsen emissions.","metaTitle":"TE 5557786-1 RJ45 Jack, 8P8C, Shielded, R/A, Cat3","metaDescription":"TE 5557786-1 modular jack, 8p8c (RJ45), shielded, right-angle through-hole, gold 50µ\" contacts.
