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.","metaTitle":"Amphenol 031-5633 BNC Jack, 50 Ohm, 1 GHz, Bulkhead Mount","metaDescription":"Amphenol 031-5633 BNC jack, female socket, 50 Ohm impedance, 1 GHz max frequency, 500 mating cycles, gold center contact.
