1274571-1 is a Mini BNC vertical jack board-mount RF coaxial connector designed for telecommunications and broadband applications. This miniature connector features a 75 ohm nominal impedance with an operating frequency range of DC to 2 GHz and a maximum VSWR of 1.16 at 1 GHz. The connector offers 500 mating cycles durability and operates within a temperature range of -40°C to +85°C. As a smaller version of the popular BNC series, it allows 40% more connections in the same area as standard BNC connectors, making it ideal for high-density PCB applications in base stations, telco DS3 networks, and instrumentation equipment.
