It features 8 positions (8P8C) with Cat 3 performance rating, suitable for 10BASE-T Ethernet connections. The shielded design with EMI grounding fingers and 4 PCB ground tabs provides effective electromagnetic interference shielding. The gold-plated phosphor bronze contacts (1.27 um over nickel) ensure reliable signal integrity and long mating cycle life. The inverted latch-up tab orientation allows the connector to be used in space-constrained applications where standard tab-down orientation is not feasible.","working_principle":"The 1955491-1 operates as a shielded RJ45 modular jack that accepts standard 8-position 8-contact (8P8C) plugs commonly used in Ethernet networking. The phosphor bronze contacts with gold over nickel plating provide low contact resistance and reliable signal transmission. The metal shield with EMI grounding fingers encloses the mated connector pair, providing a Faraday cage that attenuates radiated electromagnetic interference. The 4 PCB ground tabs provide a low-impedance path from the shield to the PCB ground plane, ensuring effective EMI shielding performance. The inverted latch-up design reverses the standard plug latch direction for applications requiring top-side plug insertion.","pin_description":"
