It carries a 500 V voltage rating and a 3 GHz maximum frequency, suiting it for moderate-bandwidth RF paths where the board launch needs a controlled 50 Ohm impedance. Gold plating on the centre contact and a Liquid Crystal Polymer dielectric keep the signal path stable across the -40°C to 90°C operating range. ## 20 Mating Cycles — A Semi-Permanent RF Connection Rated for 20 mating cycles, this jack is not built for frequent disconnect-reconnect duty. The low cycle count points to a design intended for one-time or occasional field service — the connector gets soldered to the board, mated to its counterpart, and stays. If your application requires repeated mating (test points, modular swaps), the 30-cycle A-1JB peer or the 100-cycle SMPM option offer more headroom. The silver body finish on phosphor bronze provides the RF shield, with shield termination through solder.","metaTitle":"Amphenol RF A-2JA AMMC Jack, 50 Ohm, 3 GHz, SMT, Silver Body","metaDescription":"Amphenol RF A-2JA AMMC jack, male pin, 50 Ohm impedance, 3 GHz max frequency, 500 V rating, SMT, snap-on, gold-plated centre contact.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors","RF Cable Assemblies"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"Silver","Cable Group":"-","Body Material":"Phosphor Bronze","Housing Color":"Black","Mating Cycles":"20","Mounting Type":"Surface Mount","Connector Type":"Jack, Male Pin","Fastening Type":"Snap-On","Insertion Loss":"-","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"AMMC","Frequency - Max":"3 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"A-2J","Contact Termination":"Solder","Dielectric Material":"Liquid Crystal Polymer (LCP)","Operating Temperature":"-40°C~90°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1700","stockQuantity":30,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/6d3aba09d88fc9e1f81e9710b43944e7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the impedance and frequency range of the A-2JA?","answer":"The A-2JA is a 50 Ohm jack rated to 3 GHz maximum frequency, making it suitable for moderate-bandwidth RF interconnects."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/A-2JA","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/A-2JA when reusing this data.
