This is common in Wi-Fi, ISM-band, and spread-spectrum radio applications where the antenna port is keyed to prevent accidental mating with a standard TNC. ## Mounting and Hardware — What Ships in the Bag This is a bulkhead-mount jack with a front-side nut, designed to install through a panel from the outside. The lockwasher sits between the nut and the panel face to prevent the connector from loosening under vibration — don't skip it. The mounting feature is bulkhead with a through-hole right-angle solder cup termination: the center contact and shield both terminate to the PCB via solder, while the threaded body clamps to the panel. Mounting type is panel mount, through hole, right angle — the jack body sits perpendicular to the board edge, with the solder cup terminals protruding through plated holes. ## Signal Path and Durability Specs Insertion loss is 0.18 dB at the rated frequency band, and the voltage rating is 500 V. The gold-over-nickel center contact handles the 500 mating cycles without fretting corrosion — gold is the right choice for field-serviceable connections that get unmated and remated during installation or maintenance.","metaTitle":"Amphenol RF 122490RP RP-TNC Jack, 50 Ohm, 11 GHz, Bulkhead","metaDescription":"Amphenol RF 122490RP RP-TNC jack, 50 Ohm, panel mount through-hole right angle, solder cup, gold center contact, 11 GHz, 500 cycles.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Package":"Bulk","Features":"-","Includes":"3 pcs - 1 Connector, 1 Lockwasher, 1 Nut","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"-","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Panel Mount, Through Hole, Right Angle","Connector Type":"Jack, Male Pin","Fastening Type":"Threaded","Insertion Loss":"0.18dB","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"RP-TNC","Frequency - Max":"11 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"122490","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.3100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/1d953896ef6706f0416beb5ebd2ca9fc.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/122490RP/alternatives.json"},"ai":{"faq":[{"question":"What is the connector type and impedance of the 122490RP?","answer":"The 122490RP is an RP-TNC jack with a 50 Ohm impedance, rated to 11 GHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/122490RP","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/amphenol/122490RP when reusing this data.
