75 Ohm BNC Jack, 12 GHz — Built for Broadcast and 12G-SDI
The BNC(75)-PLR-PC-12G-1: This is not the common 50 Ohm BNC used in RF test gear; the impedance mismatch between a 50 Ohm plug and a 75 Ohm jack will cause a return loss spike that kills signal quality at 12 GHz. Rated to 12 GHz, it covers 12G-SDI (which runs at 12 Gbps) and the full SMPTE video frequency range.
12 GHz Bandwidth — What It Means for 12G-SDI
The 12 GHz frequency ceiling covers the 12G-SDI data rate. The 75 Ohm impedance is non-negotiable for SDI: SMPTE standards call for 75 Ohm throughout the signal chain. This jack is built for that 75 Ohm broadcast chain.
Mounting and Termination — Right-Angle PCB with Flange
The mounting type is panel mount, through hole, right angle — the connector body sits flush against the panel face via the flange, and the solder tails go through the PCB at a right angle. The flange takes the mechanical load from cable strain and mating cycles, so the solder joints see less shear. Shield termination is solder — you solder the cable braid to the shell, which gives a solid ground path up to 12 GHz. BeCu gives good spring properties for the socket contact.
The body is zinc alloy with a nickel finish — zinc alloy is standard for BNC connectors, and the nickel plating gives a corrosion-resistant silver appearance. The housing color is silver. The package is tray.
