The 142-0701-876 is an SMA jack assembly end-launch connector designed for high-frequency RF applications. It features a 50-ohm impedance characteristic and operates across a frequency range of 0 to 18 GHz, with a maximum working voltage of 335 VRMS at sea level and a dielectric withstanding voltage of 1000 VRMS minimum. The connector utilizes beryllium copper contacts with gold plating over nickel and copper, a Teflon insulator, and brass body components, ensuring excellent electrical performance and corrosion resistance. The assembly is rated for 500 mating cycles minimum durability and operates reliably across a temperature range of -65°C to +85°C, making it suitable for demanding aerospace, military, and telecommunications applications requiring robust RF connectivity.
