131-9701-211 is a non-magnetic SMB jack assembly connector designed for vertical PC board mounting with 50-ohm impedance and 0-4 GHz frequency range capability. The connector features a copper alloy body and contacts with gold plating (0.00005 inches minimum over copper plating) and a Teflon insulator, providing excellent electrical performance and corrosion resistance. It is rated for a maximum working voltage of 335 VRMS at sea level with a dielectric withstanding voltage of 1000 VRMS minimum, and maintains contact resistance of 6 milliohms maximum for the center contact and 1 milliohm maximum for the outer conductor in initial condition. The connector is designed for RF applications requiring reliable, low-loss connections and meets or exceeds MIL-PRF-39012 environmental standards, including thermal shock, corrosion, shock, and vibration testing, with a minimum durability rating of 500 mating cycles.
