BNC Panel Jack for RF Signal Paths
The 413476-2: Mounting is bulkhead-style with a front-side nut, plus through-hole solder posts for the signal and shield connections. The shield termination is solder as well — no crimp ferrule here, so plan for a soldering step if you're integrating this into a cable assembly or PCB.
50 Ohm vs 75 Ohm — This One Is 50
This jack is 50 Ohm, not 75 Ohm. That matters because a 50 Ohm BNC has a different centre conductor diameter and dielectric geometry than a 75 Ohm version — they don't mate cleanly for RF performance, and swapping them on a 50 Ohm line introduces a mismatch that shows up as return loss. If your system is 50 Ohm — most RF test, telecom, and broadcast gear — this is the right impedance.
Sourced through independent distribution channels. The package is Tube, and the features include a board guide, filter, and isolated construction — the filter variant means this jack includes integrated filtering components for EMI suppression, which is useful when you're routing RF through a panel that also carries noisy digital lines.
