The Cat3 rating caps this jack at 16 MHz signal bandwidth, suitable for 10BASE-T Ethernet and analog phone lines. If you're routing 100BASE-TX or PoE, you need a Cat5e or higher jack — the unshielded construction and contact geometry here won't hold the impedance and crosstalk margins at 100 MHz. The 50.0µin gold finish gives you 750+ mating cycles before the contact resistance drifts, so it's a solid choice for field-serviceable panels where the cable gets swapped quarterly. ## Board Layout Notes The tab direction is down — the latch on the RJ45 plug clicks downward, which is standard for most vertical-panel cutouts.","metaTitle":"TE 5557785-1 RJ45 Jack, 8P8C, R/A, Unshielded, Cat3","metaDescription":"TE Connectivity 5557785-1 modular jack, 8P8C (RJ45), right-angle, unshielded, Cat3 rated.

Shielded jacks add a metal housing that connects to the PCB ground plane, reducing radiated emissions and improving noise immunity in high-EMI environments. Unshielded jacks are lighter, cheaper, and simpler to solder, but rely on the cable's twisted-pair balance for signal integrity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/5557785-1","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/5557785-1 when reusing this data.
