The 300 MHz maximum frequency is the practical upper limit for the UHF interface design; beyond that, the non-constant impedance causes standing-wave losses that degrade signal integrity. ## Silver-Plated Brass Center Contact, Solder Cup Termination The center contact is brass with silver plating — a standard combination for UHF connectors that balances conductivity with cost. Silver plating provides lower contact resistance than tin but tarnishes over time; the 500 mating cycle rating assumes the silver surface is wiped clean on each mate. The solder cup termination accepts tinned stranded wire directly — no crimp tool needed, but the joint must be inspected for cold solder.","metaTitle":"83-1R-RFX Amphenol RF UHF Receptacle, 500 V, 300 MHz","metaDescription":"83-1R-RFX Amphenol RF UHF receptacle, female socket, panel mount with flange, threaded fastening, solder cup termination, 500 V, 300 MHz max, 500 mating","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors","RF Cable Assemblies"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Package":"Bulk","Features":"-","Includes":"-","Impedance":"Non-Constant","Body Finish":"Nickel","Cable Group":"-","Body Material":"Zinc Die Cast","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Panel Mount","Connector Type":"Receptacle, Female Socket","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"UHF","Frequency - Max":"300 MHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Flange","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"83-1","Contact Termination":"Solder Cup","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Silver","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.1500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d76d5d98e472811953eeb3cf94dfcde1.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/83-1R-RFX/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/83-1R-RFX","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/amphenol/83-1R-RFX when reusing this data.
