It's the female socket side of the BNC interface, accepting a standard BNC plug. The 500 V rating and 0.2 dB insertion loss at 1 GHz put it in the general-purpose RF interconnect class, good for test equipment, telecom gear, and instrumentation where you need a quick-connect coaxial line that stays put under vibration. ## Mounting and Termination — What You Get in the Box The body is zinc die-cast with a nickel finish — the black and silver housing colour is standard for BNC. Termination is solder cup on the centre contact and shield, so you'll need a soldering iron on site. A board lock feature is listed, which means the solder cup tail has a small barb or shoulder that helps hold it in the PCB hole during soldering — handy if you're bench-assembling rather than using a fixture. ## Signal Performance — What 1 GHz and 0.2 dB Mean Here Rated to 1 GHz with 0.2 dB insertion loss, this jack handles baseband video, clock signals, and sub-GHz RF cleanly.","metaTitle":"Amphenol RF 031-5539-RFX BNC Jack, 50 Ohm, 1 GHz","metaDescription":"Amphenol RF 031-5539-RFX BNC jack, 50 Ohm, rated to 1 GHz.
