The SMB Series is a sub-miniature providing a fast and reliable connection for microwave applications up to 4 GHz with
high packing density. They use a snap-on mating to reduce installation time. Various plating options In nickel, gold, and tin
lead. Selective plating provides corrosion resistance finish and good solder ability characteristics.
