RF Interconnect for Video and Telecom — 5414651-3 BNC Jack
The 2 GHz ceiling suits video distribution, baseband telecom, and instrumentation where the signal stays below the UHF band.
What the 2 GHz and 500-Volt Ratings Mean for Your Build
The 2 GHz frequency ceiling is the 3 dB roll-off point for the BNC interface with this dielectric. 500 mating cycles with gold-on-phosphor-bronze contacts means the centre socket survives repeated reconnection without losing spring force. If your field techs mate and unmate this connector weekly, you get about ten years of service before the contact resistance drifts. The bayonet lock is faster than a threaded SMA but less vibration-proof — for a fixed rack installation it's fine; for a mobile platform with constant shock, a threaded interface would be the safer call.
Build Notes for the Harness and Panel Shop
The shield termination is solder — the braid or foil drain wire must be tinned and soldered to the body cup, not crimped. The right-angle through-hole tails for the centre contact and board locks feed into the PCB; the front-side nut clamps the bulkhead from the outside of the panel. Tube packaging means 5414651-3 ships in a rigid plastic tube, not tape-and-reel — fine for hand-load or low-volume selective solder, but not a pick-and-place feeder option.
