The right-angle PCB mount with a bulkhead front-side nut lets the connector sit flush against a chassis wall, saving interior space while the board lock anchors it through wave solder. ## Mounting and Termination Detail This BNC jack mounts through a panel hole and secures with a front-side nut (bulkhead style), while the right-angle PCB tails solder into the board. The isolated body means the shell is not tied to the PCB ground plane internally, which helps prevent ground loops in sensitive RF measurements — the ground path is through the shield solder tabs only. ## Contact Design and Mating Cycle Life The 500-cycle rating means this jack is built for frequent reconnection in lab, test bench, or field-service environments where cables are swapped regularly. ## Peer Comparison — 031-5538-10RFX The key difference is packaging: the 031-5540-1010 ships in a tray, while the 031-5538-10RFX ships in bulk. Both are active and electrically identical — the choice comes down to handling preference on the assembly line. The 31-5640-1010 and 31-5431 are also parametric matches but lack the isolated feature and board lock respectively.","metaTitle":"031-5540-1010 BNC Jack, 50 Ohm, 1 GHz","metaDescription":"031-5540-1010 BNC jack, female socket, 50 Ohm impedance, 1 GHz max frequency, 0.2 dB insertion loss, 500 mating cycles, right-angle PCB mount with board lock.","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":"Tray","Features":"Board Lock, Isolated","Includes":"-","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"-","Body Material":"Zinc","Housing Color":"Black, Silver","Mating Cycles":"500","Mounting Type":"Panel Mount, Through Hole, Right Angle","Connector Type":"Jack, Female Socket","Fastening Type":"Bayonet Lock","Insertion Loss":"0.2dB","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"BNC","Frequency - Max":"1 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"031-55","Contact Termination":"Solder","Dielectric Material":"Polypropylene (PP)","Operating Temperature":"-55°C~85°C","Center Contact Plating":"Gold","Center Contact Material":"Phosphor Bronze"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.0600","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/031-5540-1010/alternatives.json"},"ai":{"faq":[{"question":"Where to buy 031-5540-1010?","answer":"Submit a request for quote to confirm current availability and pricing for your required quantity."},{"question":"Does 031-5540-1010 have a board lock?","answer":"Yes, the 031-5540-1010 includes a board lock feature to secure the connector during soldering and resist vibration after assembly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/031-5540-1010","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/031-5540-1010 when reusing this data.
