The silver-plated beryllium copper centre contact and PTFE dielectric keep the impedance steady across that band. Rated for 5000 mating cycles, which is well above the typical 500-cycle BNC. That cycle life points to a connector meant for test equipment, instrumentation panels, or field-swappable modules where the cable gets disconnected regularly. The nickel-plated brass body and silver centre contact hold up to repeated connect-disconnect without the plating wearing through to base metal. The shield termination is solder — you're soldering the braid to the shell, not relying on a crimp ferrule, which gives a lower DC resistance ground path at the cost of a slower assembly step. ## BNC-R-PC(40) vs BNC-R-PC(50) The BNC-R-PC(50) shares the same 50 Ohm impedance and BNC jack form factor, but the suffix difference — (40) vs (50) — typically indicates a plating or material variant in Hirose's BNC-R series. The (40) carries silver centre contact plating; the (50) may use a different centre contact finish. For RF signal paths, the plating grade affects contact resistance and intermodulation performance at higher frequencies, so confirm the BOM's required plating before substituting.","metaTitle":"Hirose BNC-R-PC(40) BNC Jack, 50 Ohm, 2 GHz, Through Hole","metaDescription":"Hirose BNC-R-PC(40) BNC jack, female socket, 50 Ohm impedance, 2 GHz max frequency, through-hole solder termination, 5000 mating cycles.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Series":"-","Package":"Bulk","Features":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"-","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"5000","Mounting Type":"Through Hole","Connector Type":"Jack, Female Socket","Fastening Type":"Bayonet Lock","Insertion Loss":"-","Product Status":"Active","Connector Style":"BNC","Frequency - Max":"2 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"BNC-R-PC","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-55°C~85°C","Center Contact Plating":"Silver","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.0700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/99bf75fea6c1434773261f53de8d9b9d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I purchase BNC-R-PC(40)?","answer":"BNC-R-PC(40) is sourced to order against an RFQ through independent distribution.
