It is rated Cat3, which limits the signal path to voice and 10BASE-T Ethernet — not suitable for Cat5e or higher data rates. The jack is unshielded and does not contain an LED, keeping the footprint clean for basic connectivity. ## SMT Retention and Board Fit Contacts are gold flash over copper alloy — the flash plating handles the moderate mating cycle count of a handset jack without excessive cost. Single-port, single-row configuration.","metaTitle":"Molex 0955036451 Jack, 4p4c, Cat3, SMT, Vertical","metaDescription":"Molex 0955036451 modular jack, 4p4c (RJ9/RJ10/RJ22), Cat3 rated, unshielded, SMT vertical mount with board lock.
