The BNC7T-J-P-GN-ST-TH2D: The 75 Ohm impedance makes this a fit for broadcast video, HD-SDI, and other serial digital video paths where 50 Ohm would introduce a mismatch.
Through-Hole Mounting and Solder Termination
This jack mounts through the PCB — the center pin and shield legs go into plated through-holes and get soldered on the opposite side. No press-fit or surface-mount reflow here; it's a straightforward wave-solder or hand-solder part for boards that need a reliable 75 Ohm video input.
The BNC7T-J-P-GN-ST-TH2D uses a gold body finish. The sibling BNC7T-J-P-HN-ST-TH2D swaps that for a nickel body finish — same brass base material, same electrical specs, same 12 GHz and 75 Ohm rating. The choice comes down to the environment: nickel holds up better in outdoor or humid conditions, gold is standard for clean indoor gear. If you need a bulkhead mount instead of PCB mount, the BNC7T-J-P-GN-RA-BH1 gives you the same gold body and electricals but mounts through a panel with a lockwasher and nut.
