RF Specs and Fit
50 Ohm nominal impedance, 4 GHz max frequency — standard BNC performance for RF test equipment, video distribution, and telecom interconnect. Panel mount with a bulkhead cutout; the front-side nut and lockwasher are included. The center contact terminates via solder — expect to solder the center pin to a coax or PCB trace. Through-hole mounting for the center pin; no press-fit or SMT option.
