This specific variant is a kit that includes the connector body, end cap, ferrule, and insulator — four pieces total — so you get everything needed to terminate one cable end in one order line. The snap-on fastening type provides quick connect-disconnect without tools — useful for field-replaceable modules or test points — but the 100-cycle mating rating means it is designed for moderate reconnect duty, not daily production test cycling. ## Cable Group and Termination Details This SMP plug is built for the RD-316 cable group, which covers RG-316/U and equivalent 50 Ohm coax with a 0.102-inch (2.6 mm) dielectric diameter. The dielectric material is PTFE, which maintains stable impedance and low loss up to the rated frequency. Beryllium copper centre contact material provides spring retention in the socket, holding the mating pin under vibration without permanent set.","metaTitle":"SMP-FR-B2 Amphenol RF SMP Plug, 50 Ohm, 26.5 GHz","metaDescription":"Amphenol RF SMP-FR-B2 SMP plug, female socket, 50 Ohm impedance, 26.5 GHz max frequency, RD-316 cable group, 100 mating 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":"4 pcs - 1 Connector, 1 End Cap, 1 Ferrule, 1 Insulator","Impedance":"50Ohm","Body Finish":"Gold","Cable Group":"RD-316","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"100","Mounting Type":"Free Hanging (In-Line), Right Angle","Connector Type":"Plug, Female Socket","Fastening Type":"Snap-On","Insertion Loss":"-","Product Status":"Active","Connector Style":"SMP","Frequency - Max":"26.5 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"SMP-FR","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1700","stockQuantity":16,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/4d54f10300cab58b436d13dad01063b0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the SMP-FR- 50 ohm impedance?","answer":"Yes, the SMP-FR- is rated for 50 Ohm impedance, matching standard RF system impedance for most microwave and telecom applications."},{"question":"How many mating cycles does the SMP-FR- support?","answer":"The SMP-FR- is rated for 100 mating cycles, suitable for moderate reconnect duty in field-service or module replacement scenarios."},{"question":"Does the SMP-FR- come with all required parts?","answer":"Yes, the SMP-FR- is a kit that includes 4 pieces: 1 connector body, 1 end cap, 1 ferrule, and 1 insulator — everything needed to terminate one cable end."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/SMP-FR-B2","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/SMP-FR-B2 when reusing this data.
