A51-428-3196220 is a 50 Ohm SSMB right angle plug RF connector designed for use with RG178/U and 196/U coaxial cables. This microminiature snap-on connector features a gold-plated body and operates at frequencies up to 4 GHz, with a temperature rating of -65°C to 165°C. The connector body is constructed from brass with beryllium copper contacts, PTFE insulators, and gold-plated center contacts. With its small size, low mass, and quick disconnect capability, this connector is ideal for airborne applications and environments where limited space prohibits the use of torque wrenches or where components must be quickly changed to minimize downtime.
