SMB

SMB Series Connectors

The SMB was developed in the 1960s out of a need for a Subminiature connector with a quick connect/disconnect interface. Slightly smaller than SMA.   The SMB's Snap-on coupling mechanism makes it a convenient and reliable solution in applications that have space constraints. Found in 50 ohm and 75 ohm versions, SMB operates in frequency ranges up to 4 GHz.
