The SMA connector series offers semi-precision, 50-ohm impedance, and a 0.25 - 36 threaded coupling. These compact 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. The connectors typically provide 500 mating cycles, with care recommended to maintain clean mating surfaces.
