DESCRIPTION

The 919-121P-51SX is an MCX crimp plug connector designed for RG-178B/U and 196A/U cable applications. It features a 50-ohm nominal impedance with a frequency range of 0-6 GHz and a maximum VSWR of 1.060 (-30.7 dB) at 0-2.5 GHz, ensuring excellent signal integrity. The connector is constructed with gold-plated brass housing, copper ferrule, beryllium copper body, and brass contacts, with a PTFE insulator, providing superior durability and corrosion resistance. It operates reliably across a temperature range of -55°C to +155°C with a minimum durability rating of 500 mating cycles and a dielectric withstanding voltage of 1000 VRMS. The crimped ferrule features a hex crimp size of 0.128 inches with contact pin to solder configuration, making it ideal for RF/microwave applications requiring robust, high-frequency connectivity in demanding environments.
