142-0711-301 is a right-angle surface mount SMA jack assembly designed for RF and microwave connector applications. The assembly features a brass contact with gold plating (0.00001 inch minimum) over nickel plating (0.00005 inch minimum) over copper plating (0.00005 inch minimum), and a beryllium copper spring contact with gold plating (0.00003 inch minimum) over nickel and copper layers. Both the dielectric and insulator are constructed from TEFLON for superior electrical performance and durability. The connector is rated for 500 mating cycles minimum and operates reliably across a temperature range of -65°C to +165°C, meeting or exceeding ML-C-39012 standards for thermal shock, corrosion, shock, and vibration resistance. This assembly is ideal for aerospace, military, and high-reliability RF applications requiring robust interconnection solutions.
