The gold-plated brass body and gold-plated center contact provide corrosion resistance and consistent surface conductivity across the 500-cycle rated mating life. The PTFE dielectric maintains a stable 75 Ohm impedance through the connector body, and the insertion loss is specified at 0.3 dB up to the 4 GHz ceiling — a tight figure that keeps the signal budget intact for a single in-line connection. The center contact terminates to a coaxial cable center conductor through a solder cup or through-hole PCB pad; the contact termination is listed as solder, so no crimp tool is required for the center pin. The snap-on fastening type provides quick mate and unmate without tools — the mating receptacle (typically an SMB jack or plug on a cable assembly) clicks into place and releases with a straight pull. The 500-cycle rating is typical for SMB and suits test-point or field-service connections where the cable is disconnected periodically.","metaTitle":"Amphenol RF 142204-75 SMB Receptacle, 75 Ohm, 4 GHz","metaDescription":"Amphenol RF 142204-75 SMB receptacle, male pin, 75 Ohm impedance, 4 GHz max frequency, 0.3 dB insertion loss, 500 mating cycles, panel mount with included","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":"75Ohm","Body Finish":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Panel Mount, Through Hole","Connector Type":"Receptacle, Male Pin","Fastening Type":"Snap-On","Insertion Loss":"0.3dB","Product Status":"Active","Voltage Rating":"335 V","Connector Style":"SMB","Frequency - Max":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"142204","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":"$2.1614","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/aea3ea1dda656bf66d0a3b6ca563e356.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/142204-75/alternatives.json"},"ai":{"faq":[{"question":"Is 142204-75 available via RFQ confirmation?","answer":"The 142204-75 is an active-production part sourced to order through independent distribution."},{"question":"What cable does 142204-75 mate with?","answer":"The 142204-75 mates with any SMB plug or jack that uses the standard snap-on interface and is designed for 75 Ohm cable — typically RG-59, RG-6, or similar 75 Ohm coax.
