The 4 GHz max frequency means this jack can pass signals up into the low microwave range, covering Wi-Fi bands, cellular, and instrumentation signals without significant roll-off. The 0.2 dB insertion loss at rated frequency is typical for a BNC interface at this price point — it's low enough that you won't see a meaningful signal drop in a short cable run or a single board-to-board interconnect. ## Construction and Termination Details The shield termination is solder, same as the center contact, so you'll need to solder both the signal pin and the ground shield to the PCB. The body is zinc die cast with a tin finish, which is a standard industrial finish — it's not as corrosion-resistant as nickel, but it's fine for indoor equipment.","metaTitle":"Amphenol RF 31-5329 BNC Jack, Female Socket, 50 Ohm, 4 GHz","metaDescription":"Amphenol RF 31-5329 BNC jack, female socket, through-hole, 50 Ohm impedance, 4 GHz max frequency, 0.2 dB insertion loss, 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":"Amphenol RF","Series":"-","Package":"Bulk","Features":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"Tin","Cable Group":"-","Body Material":"Zinc Die Cast","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Through Hole","Connector Type":"Jack, Female Socket","Fastening Type":"Bayonet Lock","Insertion Loss":"0.2dB","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"BNC","Frequency - Max":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"31-532","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.6600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d7e1e4408ebdfb9d755dc1157b2f8052.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/31-5329/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance of Amphenol 31-5329?","answer":"The 31-5329 has a 50 Ohm impedance, which is the standard for RF signal paths and matches common coaxial cables like RG-58."},{"question":"Is 31-5329 compatible with RG-58 cable?","answer":"The 31-5329 is a PCB-mount jack, not a cable-mount connector, so it doesn't directly terminate to RG-58 cable.
