The bayonet lock provides quick connect/disconnect with positive retention — the standard BNC mating interface that engages with a quarter-turn. The nickel-plated zinc body gives adequate RF shielding and corrosion resistance for indoor and sheltered outdoor use. Tin plating is a cost-effective choice for moderate-duty applications — it handles the 500-cycle rating but is not intended for the high-cycle or corrosive-environment duty that gold plating would serve. This BNC jack uses a panel mount with a flange, secured through the panel cutout, and the signal and ground connections are made via through-hole solder tails on the PCB. The 'Isolated' feature indicates the connector body is electrically isolated from the mounting panel. This avoids ground loops or controls the shield path through the PCB. ## Comparison with Peers: 415420-1 and 1057230-1 The 5226978-1 shares the same BNC jack form factor and 50 Ohm impedance with the 415420-1, both in bulk packaging and active lifecycle status. The 415420-1 is a direct cross-shop candidate — same series, same basic specs — and the choice between them comes down to availability and pricing at quote time. The 1057230-1 is a higher-spec peer: it uses a gold-plated body and center contact (beryllium copper), a tetrafluoroethylene (TFE) dielectric, and is rated to 22 GHz. The gold plating on the 1057230-1 supports more mating cycles and better corrosion resistance, while the higher frequency rating suits microwave applications. The 5226978-1 with its tin-plated contact and 4 GHz ceiling is the cost-optimized choice for general-purpose RF work up to 4 GHz.","metaTitle":"TE Connectivity 5226978-1 BNC Jack, 50 Ohm, 4 GHz","metaDescription":"TE Connectivity 5226978-1 BNC jack, female socket, 50 Ohm impedance, 4 GHz max frequency, 500 V rating, 500 mating cycles.","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":"Isolated","Includes":"-","Impedance":"50 Ohms","Body Finish":"Nickel","Cable Group":"-","Body Material":"Zinc","Housing Color":"Natural, Silver","Mating Cycles":"500","Mounting Type":"Panel Mount, Through Hole, Right Angle","Connector Type":"Jack, Female Socket","Fastening Type":"Bayonet Lock","Insertion Loss":"-","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"BNC","Frequency - Max":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Flange","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"5226978","Contact Termination":"Solder","Dielectric Material":"Polymethylpentene (PMP)","Operating Temperature":"-55°C ~ 85°C","Center Contact Plating":"Tin","Center Contact Material":"Phosphor Bronze"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.8900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/971944268bf7f95eff48ac3e443d6311.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the TE Connectivity 5226978-1 BNC jack?","answer":"Current pricing and lead time are confirmed at quote time — submit an RFQ for your required quantity."},{"question":"What is the mounting style of the 5226978-1?","answer":"The 5226978-1 uses a panel mount with a flange, combined with right-angle through-hole solder termination to the PCB.
