50 Ohm BNC Jack, Right-Angle PCB Mount — 1 GHz, 500 Cycles
The 31-5431: The 1 GHz frequency ceiling and 0.2 dB insertion loss suit it for video distribution, telecom baseband, and test equipment interconnects where signal integrity matters up to the low-GHz range. The zinc die-cast body with nickel finish provides RF shielding and environmental protection in indoor equipment racks or lab setups.
Mounting and Termination — Bulkhead Feedthrough with Solder Shield
The shield termination is solder — you solder the braid or ground plane directly to the body for a low-impedance RF return path. The center contact terminates via a solder cup, making it straightforward to attach a coaxial cable center conductor. The right-angle body keeps the cable low-profile against the board, useful in tight enclosures.
Board Guide and Isolation Features
The 31-5431 includes a board guide and is listed as isolated. The isolation feature means the body is electrically isolated from the mounting panel — useful when you need to break ground loops or avoid a chassis ground connection at the bulkhead.
