50 Ohm BNC Bulkhead Jack for Sub-1 GHz Signal Paths
The 031-5633: It mounts through a panel using a bulkhead front-side nut, with the center contact and shield both terminated by solder cups.
What the 1 GHz and 0.2 dB Ratings Mean for Signal Integrity
The 1 GHz maximum frequency and 0.2 dB insertion loss define the usable bandwidth for this BNC jack. At 1 GHz, the insertion loss stays under 0.2 dB, which is typical for a BNC interface at this frequency — acceptable for instrumentation, baseband video, and low-power RF up to the UHF band. The polypropylene dielectric keeps losses low through the rated band.
Construction and Contact Reliability for 500 Mating Cycles
The zinc die cast body with nickel finish provides the RF shielding and mechanical ruggedness expected from a panel-mount BNC. The solder cup termination on both the center pin and the shield requires manual soldering, but gives a reliable connection that can be inspected before the panel nut is tightened.
