SMC

The SMC connectors have been designed with a 'threaded' coupling and have the same size as the SMB connectors. They are particularly suitable for use in high vibration environments.

This connector range is suitable for the standard ranges of flexible and semi rigid cables and is also available in PCB and panel mount versions.

The characteristic impedance of the SMC coaxial connectors is 50 ohm.

SMC coaxial connectors meet the specification of IEC 169-9 and
MIL-C-39012.
