50-Ohm BNC Bulkhead Jack, 4 GHz, Solder Cup Termination
The TE Connectivity 5227169-8 is a 50-Ohm BNC jack (female socket) in a panel-mount bulkhead configuration with a rear-side nut.
The 4 GHz maximum frequency is the practical ceiling for this BNC interface. At 50 Ohms, this jack mates with any 50-Ohm BNC plug. The 500 mating cycles, supported by the gold-plated centre contact, mean this connector is rated for repeated disconnect/reconnect in test equipment, patch panels, or field-deployed systems without contact wear becoming a failure mode.
The shield termination is a solder tag — you solder the cable braid to the tag, then the centre conductor into the solder cup. The kit includes the connector, nut, and solder tag (3 pieces total). Extended insulation on the centre contact adds creepage distance for the 500 V rating.
