The gold-plated stainless steel body handles corrosion in lab, field, or outdoor cabinet environments — the gold finish is a step above the standard passivated stainless or nickel SMA bodies you see on commodity parts. Termination is solder cup on the centre contact — you tin the centre conductor of your coax, feed it into the cup, and solder. No crimp tool required, which makes this a practical choice for prototype builds, field repairs, or short-run cable assemblies where you want a repeatable RF joint without investing in a die set. The 18 GHz frequency ceiling means this connector supports the full L, S, C, and X bands plus the lower Ku band — enough headroom for most microwave test setups, radar subsystems, and satellite communications gear up to 18 GHz. The 500-cycle rating comes from the gold-on-gold contact interface — the gold-plated beryllium copper centre contact wipes against the gold-plated centre pin of the mating plug. The extended insulation feature (noted in the spec) gives extra dielectric creepage distance between centre and outer conductor — useful in applications where the connector sees DC bias or where condensation could track across a standard insulator. ## Mounting and Cable Termination Details This is a bulkhead-mount receptacle with front-side nut installation — the connector body slides through the panel from the outside, and the nut and lockwasher tighten from behind. The panel cutout is the standard SMA bulkhead hole (0.312-inch diameter), and the lockwasher gives you a positive ground bond to the chassis. No gasket or O-ring is listed, so this is not a sealed bulkhead pass-through; keep it in dry indoor or protected outdoor enclosures unless you add your own sealing compound.","metaTitle":"TE 1-1478966-0 Greenpar SMA Receptacle, 50 Ohm, 18 GHz","metaDescription":"TE 1-1478966-0 Greenpar SMA receptacle, female socket, 50 Ohm impedance, DC-18 GHz, panel mount with bulkhead nut, gold-plated stainless steel body, solder cup","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"Greenpar","Package":"Bulk","Features":"Extended Insulation","Includes":"3 pcs - 1 Connector, 1 Lockwasher, 1 Nut","Impedance":"50 Ohms","Body Finish":"Gold","Cable Group":"-","Body Material":"Stainless Steel","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Panel Mount","Connector Type":"Receptacle, Female Socket","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Connector Style":"SMA","Frequency - Max":"18 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"1478966","Contact Termination":"Solder Cup","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.2890","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/463401dbefea22cdbed641b67a2dabb6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 1-1478966-0 compatible with standard SMA connectors?","answer":"Yes. This is a standard SMA receptacle, female socket, 50 Ohm impedance, so it mates with any male SMA plug that meets the MIL-STD-348 interface. The threaded coupling and gold-plated centre contact are fully compatible with all standard SMA hardware."},{"question":"What cable types work with the solder cup termination?","answer":"The solder cup accepts the centre conductor of any coax cable whose centre wire fits the cup diameter — typically RG316, RG174, RG58, or semi-rigid cables like.085\" or.141\" coax. The shield is soldered to the body or the shield termination cup. No specific cable type is listed in the spec, so match the centre conductor gauge to the cup size in the product drawing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1-1478966-0","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/te-connectivity-amp-connectors/1-1478966-0 when reusing this data.
