DESCRIPTION

The 142-0408-011 is an SMA straight plug assembly designed for RG-142 cable termination, featuring gold-plated brass components for superior corrosion resistance and electrical performance. The connector is rated for 50-ohm impedance with a frequency range of 0–12.4 GHz, supporting high-speed RF applications. Key electrical specifications include a contact resistance of 3.0 milliohm maximum (center conductor initial) and 2.0 milliohm maximum (outer conductor initial), with insertion loss of 0.06 dB maximum at 6 GHz. The assembly incorporates a beryllium copper unplated retention spring and brass insulator, with mechanical specifications including a mating torque of 7–10 inch-pounds and cable retention of 45 lbs minimum axial force. Operating temperature range is -65°C to +185°C, and the connector meets MIL-STD-202 environmental standards for thermal shock, corrosion, shock, vibration, and moisture resistance. This connector is ideal for military, aerospace, and high-reliability RF applications requiring robust performance in demanding environments.
