The 142-0711-826 is an SMA jack assembly end-launch connector designed for high-frequency RF applications. It features a 50-ohm impedance with a frequency range of 0–18 GHz and supports a maximum working voltage of 300 Vrms at sea level. The connector utilizes beryllium copper contacts with gold plating over nickel and copper, combined with a Teflon insulator, ensuring excellent electrical performance and durability. Key electrical specifications include a dielectric withstanding voltage of 1000 Vrms minimum, insulation resistance of 5000 megohms minimum, and center contact resistance of 3.0 milliohms maximum initially and 4.0 milliohms maximum after environmental testing. The connector is rated for 500 mating cycles minimum and operates reliably across a temperature range of -65°C to +65°C, making it suitable for demanding aerospace, military, and telecommunications applications where robust RF connectivity is essential.
