142-1711-001 is a right-angle SMA jack connector assembly with a 5.00-inch square flange mount and extended TEFLON dielectric, designed for RF and microwave applications. The connector features a brass body with gold plating over nickel and copper, combined with beryllium copper gold-plated contacts, providing excellent electrical conductivity and corrosion resistance. It operates at 50-ohm impedance across a frequency range of 0–18 GHz, with a maximum working voltage of 335 VRMS at sea level and a dielectric withstanding voltage of 1000 VRMS minimum. The connector exhibits low contact resistance (3.0 milliohm initial, 4.0 milliohm after environmental testing for center contact) and high isolation (-70 dB minimum at 2.5 GHz). With an operating temperature range of -65°C to +165°C, mating torque of 7–10 inch-pounds, and durability rated for 500 cycles minimum, this connector is ideal for military, aerospace, and high-reliability RF systems requiring robust performance in demanding environments.
