The 4 GHz maximum frequency and 0.3 dB insertion loss give it a clean passband for L-band and lower C-band work, and the 335 V rating means the dielectric stack has headroom above typical 50 Ohm signal levels. ## Construction That Survives the Board Assembly Line Gold plating on the centre contact matters here: 500 mating cycles is a solid number for a snap-on connector, and the gold-on-brass interface keeps contact resistance low over those cycles without fretting.","metaTitle":"TE Connectivity 413990-2 SMB Receptacle, 50 Ohm, 4 GHz","metaDescription":"TE Connectivity 413990-2 SMB receptacle, male pin, 50 Ohm impedance, 4 GHz max frequency, 0.3 dB insertion loss, 500 mating cycles, through-hole solder","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors","RF Cable Assemblies"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"-","Package":"Bulk","Features":"-","Includes":"-","Impedance":"50 Ohms","Body Finish":"Nickel","Cable Group":"-","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Through Hole","Connector Type":"Receptacle, Male Pin","Fastening Type":"Snap-On","Insertion Loss":"0.3dB","Product Status":"Active","Voltage Rating":"335 V","Connector Style":"SMB","Frequency - Max":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"413990","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C ~ 165°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.4500","stockQuantity":51,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9abe67b67c48a5d3bcbd9bbb8d6e6528.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the impedance of the 413990-2?","answer":"The 413990-2 is a 50 Ohm SMB receptacle, matching the standard impedance for most RF test and telecom signal paths."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/413990-2","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/te-connectivity-amp-connectors/413990-2 when reusing this data.
