The 142-0791-811 is an SMA jack self-fixture end launch connector designed for high-frequency RF and microwave applications. It features a 50-ohm impedance with a frequency range of 0–18 GHz (10 GHz maximum typical circuit board transition) and supports a working voltage of 335 VRMS maximum at sea level with a dielectric withstanding voltage of 1000 VRMS minimum. The connector is constructed with a brass body plated with gold over nickel over copper, beryllium copper contacts with gold plating, and a Teflon insulator, ensuring excellent electrical performance and corrosion resistance. It operates reliably across a temperature range of –65°C to +165°C and meets or exceeds MIL-PRF-39012 environmental standards including thermal shock, corrosion, shock, vibration, and moisture resistance testing. This connector is ideal for demanding RF/microwave systems, test equipment, and high-frequency circuit board applications requiring robust, high-performance interconnection.
