The 131-3701-211 is a straight PC-mount SMB jack assembly connector designed for RF and microwave applications. It features a 50-ohm impedance characteristic and operates across a frequency range of 0 to 4 GHz, making it suitable for high-frequency signal transmission. The connector body and contacts are constructed from brass with nickel and copper plating, while the insulator is made of Teflon for excellent dielectric properties. It is rated for a maximum working voltage of 335 VRMS at sea level and a dielectric withstanding voltage of 1000 VRMS minimum. The connector exhibits an initial disengage force of 14 lbs maximum and maintains durability through 500 mating cycles minimum, with an operating temperature range of -65°C to +65°C. This connector is ideal for PCB-mounted RF applications in telecommunications, test equipment, and instrumentation systems requiring reliable high-frequency connections.
