SMB RF connectors are semi-precision, subminiature devices that provide repeatable electrical performance from DC to 4 GHz. The SMB family of connectors provides a means of quick connect and disconnect through a snap-on type coupling. This makes them useful in areas that are inaccessible to normal mating action. They are best suited for use with cables in the range of .070" to .120" diameters, such as RG 178, RG 174, RG 316. The series is similar in size to SMC connectors but is generally used at a lower frequency. SMB type connectors are designed to conform to MIL-C-39012 specifications.
Its smaller physical size and snap-on coupling make the SMB an ideal general purpose connector where packaging density, ease of mating/unmating and economy are prerequisites. Typical applications for SMB connectors are telecommunications, test equipment, instrumentation, and GPS.
