The stainless steel body with gold finish gives it corrosion resistance suitable for repeated field mating in panel-mount applications. The 50 Ohm impedance and 18 GHz maximum frequency make this a solid choice for microwave test setups, antenna feeds, and instrumentation where the signal path stays within that band. The 500-cycle mating life is typical for an SMA with gold-over-beryllium copper contacts — the centre contact plating is gold, which keeps contact resistance stable over repeated connect-disconnect cycles in field-service or lab environments. Cable compatibility is specific: this jack is designed for RG-405 (.085\" semi-rigid) cable. The PTFE dielectric handles the temperature of soldering without degrading the impedance match. ## Mounting and hardware Panel mounting is via a bulkhead with a front-side nut — the threaded body passes through the panel cutout and the nut tightens from the front. The included gasket seals the panel interface, and the lockwasher prevents the nut from backing off under vibration. The kit approach means you don't need to source the hardware separately; the six-piece set covers the full installation.","metaTitle":"TE Connectivity 1-1478988-0 SMA Jack, 50 Ohm, 18 GHz","metaDescription":"TE Connectivity Greenpar SMA jack, female socket, 50 Ohm, DC-18 GHz, for RG-405 (.085\" semi-rigid) cable.","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":"-","Includes":"6 pcs - 1 Connector, 1 Contact, 1 Gasket, 1 Insulator, 1 Lockwasher, 1 Nut","Impedance":"50 Ohms","Body Finish":"Gold","Cable Group":"RG-405 (.085\\\" Semi Rigid)","Body Material":"Stainless Steel","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Panel Mount","Connector Type":"Jack, 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":"1478988","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.2004","stockQuantity":28,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/dcb8897b0e52f764438cbdc3a03f6660.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What cable does 1-1478988-0 work with?","answer":"This SMA jack is designed for RG-405 (.085\" semi-rigid) cable.
