The 131-1701-371 is a PC-mount assembly jack connector designed for high-frequency RF applications. It features a 50-ohm impedance with a frequency range of 0 to 4 GHz and is constructed with a zinc-plated body over nickel and copper plating, brass cold-plated contacts, and Teflon insulators for reliable performance. The connector is rated for a maximum working voltage of 335 VRMS at sea level with a dielectric withstanding voltage of 1000 VRMS minimum, and offers contact retention of 4 lbs minimum axial force with an initial engagement force of 14 lbs and durability of 500 cycles minimum. Operating over a temperature range of -65°C to +165°C and meeting MIL-STD-202 environmental standards for thermal shock, corrosion, shock, and vibration, this connector is suitable for RF/microwave instrumentation, test equipment, and precision signal transmission applications requiring robust mechanical and electrical performance.
