The 75 Ohm impedance and 2 GHz maximum frequency define the signal envelope — this plug is intended for baseband video (SDI, composite), telecom T1/, and instrumentation links where the characteristic impedance of the cable and connector must match to avoid reflections. The insertion loss is specified at 0.15 dB, a figure that holds across the band when terminated onto the correct cable group. Cable compatibility is specific: the plug is designed for AT&T 735A cable group. That means the crimp ferrule and centre contact are sized for a particular cable diameter and dielectric type — substituting a different cable without checking the fit risks poor crimp retention and impedance mismatch. The dielectric is polyethylene (PE). Termination is crimp for both the centre contact and the shield — a two-step crimp process using the correct die set for the cable group. The shield termination is a crimp ferrule that compresses over the braid; no soldering or clamp required. The connector is free-hanging (in-line), intended for cable-end installation, not panel or PCB mount. The silver housing colour is the natural nickel finish — no additional plating layer beyond the corrosion-resistant nickel on the brass body.","metaTitle":"TE Connectivity 1-221185-8 BNC Plug, 75 Ohm, 2 GHz","metaDescription":"TE Connectivity 1-221185-8 BNC plug, male pin, 75 Ohm impedance, 2 GHz max frequency, 500 mating cycles, crimp termination, nickel body, gold center contact.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"-","Package":"Bulk","Features":"-","Includes":"-","Impedance":"75Ohm","Body Finish":"Nickel","Cable Group":"AT&T 735A","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Plug, Male Pin","Fastening Type":"Bayonet Lock","Insertion Loss":"0.15dB","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"BNC","Frequency - Max":"2 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"221185","Contact Termination":"Crimp","Dielectric Material":"Polyethylene (PE)","Operating Temperature":"-55°C~85°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.3399","stockQuantity":35,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d6bd73d46cb0dc68a808f22cabe5dcf9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What cable types are compatible with 1-221185-8?","answer":"The 1-221185-8 is designed for the AT&T 735A cable group.
