The centre contact is gold-plated copper alloy, soldered to the cable centre conductor; the shield is crimped to the zinc body with a nickel finish. ## Mating and Durability Threaded coupling provides vibration-resistant mating — standard for SMA. The bulkhead front-side nut mounting allows the connector to be secured from outside the panel, simplifying installation in enclosures where rear access is limited. Buyers maintaining a stock of RG-178/196 SMA jacks should evaluate a last-time-buy quantity or identify a form-fit-function alternative from the KOAXXA or equivalent SMA series.","metaTitle":"TE KOAXXA 1-2081204-1 SMA Jack, 50 Ohm, 18 GHz, Obsolete","metaDescription":"TE Connectivity KOAXXA 1-2081204-1 SMA jack, female socket, 50 Ohm, 18 GHz max, RG-178/196.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"KOAXXA","Package":"Bulk","Features":"-","Includes":"4 pcs - 1 Connector, 1 Ferrule, 1 Lockwasher, 1 Nut","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"RG-178, 196","Body Material":"Zinc","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Panel Mount","Connector Type":"Jack, Female Socket","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Obsolete","Voltage Rating":"335 V","Connector Style":"SMA","Frequency - Max":"18 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"2081204","Contact Termination":"Solder","Dielectric Material":"Polymethylpentene (PMP)","Operating Temperature":"-65°C~85°C","Center Contact Plating":"Gold","Center Contact Material":"Copper Alloy"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.7800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is 1-2081204-1 obsolete?","answer":"Yes, TE Connectivity lists 1-2081204-1 as Obsolete.
