If you drop this jack into a 50 Ohm system, the impedance step will cause a reflection at the junction, eating into your signal budget above a few hundred MHz. The 4 GHz bandwidth is plenty for HD-SDI (3 GHz) or DOCSIS upstream carriers, but not for Ku-band satellite IF or 5G mid-band. ## Temperature Range and Build Quality The PTFE dielectric holds its dielectric constant across that span, so the impedance stays stable. The beryllium copper centre contact retains its spring force after repeated thermal cycles — important for a connector that lives in an equipment rack that heats up and cools down daily.","metaTitle":"Amphenol RF 282127-75-10 1.0/2.3 Jack, 75 Ohm, 4 GHz","metaDescription":"Amphenol RF 282127-75-10 1.0/2.3 jack, female socket, 75 Ohm impedance, 4 GHz max frequency, 500 mating cycles, through-hole solder termination.","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":"-","Impedance":"75Ohm","Body Finish":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Through Hole","Connector Type":"Jack, Female Socket","Fastening Type":"Push-Pull","Insertion Loss":"-","Product Status":"Active","Connector Style":"1.0/2.3","Frequency - Max":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"282127","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":"$12.6371","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f4d2e75993cfd72417b570dd8c1a0aa4.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/282127-75-10/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 282127-75-10?","answer":"The 282127-75-10 is sourced to order through independent distribution.
