The 1-1478032-0: Rated to 2 GHz maximum frequency and 500 V, this jack carries the 75 Ohm characteristic impedance that distinguishes it from the more common 50 Ohm BNC used in RF and telecom; the 75 Ohm variant is the correct choice for composite video, SDI, and analogue broadcast distribution where impedance mismatch causes return loss and ghosting. The mounting arrangement is a bulkhead front-side nut with a right-angle through-hole PCB tail — the signal enters perpendicular to the board, saving height in a shallow enclosure.
