SMA - Miniature Coaxial Connectors (MIL-C-39012) 'Standard'
SMA miniatire coaxial connecor is ideal for microwave frequency of 18 GHz and higher. The high quality finish and optimum eletrical properties meet the equirements of MIL C-39012.
The difference between the standard and special versions lies in the choice of materials. The special version differs housing elements made of copper beryllium or stainless steel for higher mechanical strength.
