031-5329 is a BNC straight printed circuit board jack connector designed for 50O RF applications. It features a nickel-plated brass body with gold-plated beryllium copper contacts and a blunt post (flush) mounting style suitable for PCB integration. The connector is rated for industrial-grade applications and accommodates a 3-leg long post terminal measuring 0.040 inches (1.0 mm) in diameter and 0.125 inches (3.2 mm) long, with a 0.025-inch (0.6 mm) flush depth. BNC connectors are miniature quick-connect/disconnect RF connectors usable up to 11 GHz with low reflection through 4 GHz, making them ideal for cable termination and PCB-mounted RF signal distribution in test equipment, instrumentation, and communication systems.
