It is a same-series adapter — both ends are BNC, so it splits one signal path into two without changing connector family. The T-shape body is free-hanging (in-line mount), designed for panel-free cable routing where a straight barrel would not give you the branch. ## RF performance and construction Gold on the mating surfaces delivers the 500-cycle mating life — the contact resistance stays consistent through repeated reconnections in field-service or test-bench use. The bayonet lock on both ends gives a quarter-turn positive mate that holds under cable strain. ## How it differs from a standard BNC barrel adapter A standard BNC barrel adapter (plug to jack, straight) simply extends a cable run — signal in one end, out the other. The 1-1337458-0 T adapter takes a single BNC plug input and splits it to two BNC jacks, creating a signal branch point. Both paths carry the full 50 Ohm signal simultaneously. The T-shape body means it sits perpendicular to the cable axis rather than inline, so it needs clearance for the branch leg. If you only need a straight pass-through, a barrel adapter is the simpler fit; if you need to tap a signal to a second instrument or monitor, this T adapter is the part.","metaTitle":"TE Greenpar 1-1337458-0 BNC T Adapter, 50 Ohm, 4 GHz","metaDescription":"TE Connectivity Greenpar 1-1337458-0 BNC T adapter, 50 Ohm impedance, 4 GHz max frequency, nickel body, gold center contacts, 500 mating cycles.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"T-Shape","Series":"Greenpar","Package":"Bulk","Features":"-","Includes":"-","Impedance":"50 Ohms","Body Finish":"Nickel","Adapter Type":"Plug to Jack","Body Material":"Brass","Center Gender":"Female to Male","Mating Cycles":"500","Mounting Type":"Free Hanging (In-Line)","Adapter Series":"BNC to BNC, Dual","Fastening Type":"Bayonet Lock, Bayonet Lock","Insertion Loss":"-","Product Status":"Active","Conversion Type":"Same Series","Frequency - Max":"4 GHz","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Base Product Number":"1337458","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C ~ 165°C","Center Contact Plating":"Gold","Center Contact Material":"Brass","Convert To (Adapter End)":"BNC Jack, Female Socket (2)","Convert From (Adapter End)":"BNC Plug, Male Pin"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.9703","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/554e7b095a547d2eb40b6a8f5f818579.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1-1337458-0/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance of 1-1337458-0?","answer":"50 Ohms, which is the standard impedance for BNC video, RF test, and telecom signal paths.
