The UBJ48 is a 75Ω insulated, feed-through TNC bulkhead jack from the miniature coax threaded 40/240 series. It is configured as a right-angle TNC receptacle intended for circuit board mounting. This component is designed for bulkhead installation, requiring a D3.156 style mounting hole. Its insulated, feed-through design allows signals to pass through a panel directly to a PCB while maintaining electrical isolation from the chassis, making it ideal for applications requiring secure, panel-mounted coaxial connections.
