The 50 Ohm impedance is held through a PTFE dielectric, and the connector is rated to 11 GHz, covering L-band through X-band frequencies. A 1500 V voltage rating sets it apart from typical N Type connectors, which usually top out at 1000 V, making this part suited for high-power RF or pulsed signal paths where voltage standoff is the limiting factor. The 11 GHz maximum frequency is the practical ceiling for this connector; above that, the N Type interface geometry starts to support higher-order modes that degrade VSWR. For a clean 50 Ohm path up to 11 GHz, the solder cup termination must be executed with consistent center-conductor standoff and minimal solder voiding. The 500 mating cycles rating, backed by gold-over-nickel plating on the center contact, means this receptacle can survive years of field reconnections in test racks or antenna line-ups before contact wear becomes a concern. The weatherproof ingress protection (IP-rated per the manufacturer's definition) allows outdoor panel mounting without a separate boot or gasket, as long as the mating plug is also weatherproof. ## Mounting and Termination: Panel Flange and Solder Cup The shield is terminated to the chassis or cable braid through the solder cup on the outer conductor — a reliable method for high-power or high-vibration installations where a crimp might loosen. The center contact uses a separate solder cup, requiring the cable center conductor to be tinned and inserted before soldering.","metaTitle":"000-49000-SRFX N Type Receptacle, 50 Ohm, 11 GHz","metaDescription":"Amphenol RF 000-49000-SRFX N Type receptacle, male pin, 50 Ohm impedance, 11 GHz max frequency, 1500 V rating, 500 mating cycles, weatherproof, gold-plated","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":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"Silver","Cable Group":"-","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Panel Mount","Connector Type":"Receptacle, Male Pin","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Voltage Rating":"1500 V","Connector Style":"N Type","Frequency - Max":"11 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Flange","Ingress Protection":"Weatherproof","Shield Termination":"Solder","Base Product Number":"000-49","Contact Termination":"Solder Cup","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.9500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d5c9b3a96a2be7570beb663820806060.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/000-49000-SRFX/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance of 000-49000-SRFX?","answer":"The impedance is 50 Ohm, standard for N Type connectors, matched to most RF test and telecom systems."},{"question":"Is 000-49000-SRFX an SMA connector?","answer":"No, this is an N Type connector, not SMA.
