50 ohm 0-10 GHz
SMC connectors are similar to the SMB in general size and performance, but feature threaded couplings rather than snap-on types.
As with the SMB size, reliable performance, and moderate cost make the SMC an excellent consideration where packaging density is a must. Its threaded coupling ensures peak performance in applications where vibration or shock may be a design consideration.
