The 0.3 dB insertion loss is typical for an SMB interface at these frequencies. Snap-on coupling means quick field mating without tools, but the retention is less positive than a threaded SMA — the 500-cycle rating is a practical limit for repeated connect-disconnect in test or field-service scenarios. The voltage rating is 335 V. ## Comparison with 415218-1 The 415218-1 is also an SMB receptacle in Bulk package with Active lifecycle — same connector style and basic form factor. The difference is in the center contact material and plating details; the 413990-1 uses gold-plated brass center contact, while the 415218-1 may differ. For a form-fit-function cross, verify the center contact spec against your application before substituting.","metaTitle":"TE Connectivity 413990-1 SMB Receptacle, 50 Ohm, 4 GHz, Gold","metaDescription":"TE Connectivity 413990-1 SMB receptacle, male pin, through-hole, 50 Ohm impedance, 4 GHz max frequency, 500 mating cycles, gold body.","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":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Gold","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":"$6.5500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is 413990-1 active or obsolete?","answer":"The 413990-1 carries an Active lifecycle status per the manufacturer — full production, no end-of-life notice."},{"question":"What is the impedance of 413990-1?","answer":"The 413990-1 is a 50 Ohm SMB receptacle, rated to 4 GHz maximum frequency with 0.3 dB insertion loss."},{"question":"What is the alternative to 413990-1?","answer":"The closest peer is the 415218-1, also an SMB receptacle in Bulk package with Active lifecycle — but the center contact material and plating may differ, so confirm form-fit-function before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/413990-1","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/413990-1 when reusing this data.
