Product details

75 Ohm BNC for Video and Data — What Sets This One Apart

The 031-70577-12G: It carries a 12 GHz frequency ceiling, which is unusually high for a 75 Ohm BNC — most 75 Ohm parts top out around 1-2 GHz, so this one is specced for higher-bandwidth signals like 4K/8K video or serial digital interfaces.

Construction and Termination — What You Get in the Bag

Termination is solder for both the center pin and the shield — no crimp tool needed, but you'll want a clean soldering iron and a steady hand on the center contact. The package is a bag, so it ships loose, not on a tape reel.

Frequently asked questions

Is 031-70577-12G 50 or 75 ohm?

The impedance is specified as 75 Ohm, which means it is designed for video, broadcast, and data applications — not for standard RF test equipment or radio systems.

Does 031-70577-12G have a bayonet lock?

Yes, the fastening type is bayonet lock — the standard BNC quarter-turn coupling. It mates and unmates quickly without threads, and the 500-cycle rating means the locking groove is designed for repeated field use.
