The 112740-12: At 4 GHz max frequency with 0.2 dB insertion loss, it carries composite video, SDI, or RF carriers without the impedance mismatch a 50 Ohm BNC would introduce.
Mounting Hardware and Installation
The mounting type is listed as both board edge, end launch and panel mount, so it can also be soldered directly to a PCB edge for a clean RF launch.
Dielectric and Temperature Range
That temperature span covers outdoor enclosures, engine compartments, and industrial ovens; the PTFE won't cold-flow or soften at the extremes. The voltage rating is 500 V, adequate for the signal levels in video and telecom gear, though the limiting factor at 4 GHz is the dielectric breakdown at the launch, not the bulk rating.
