The SMA connector range offers semi-precision performance with a 50-ohm impedance and a 0.25 - 36 threaded coupling. These compact Sub Miniature version A connectors are frequently used as a standard for antennas, devices, and various medical applications. They are also known as F type coaxial connectors and are suitable for relatively small electronic equipment. These connectors are designed for approximately 500 mating cycles, with care required to maintain clean mating surfaces.
