MC-Card series are microminature,50-ohm connectors that feature snap-on mating and a frequency range of DC-6GHz.
MC-Card connectors are an alternative to MMCX connectors in many wireless and telecom applications.
They are similar to MMCX in performance, feature quick snap-on mating and unmating, and designed to withstand a minimum of 5,000 mating cycles.
Delta MC-Card connectors are available for several sizes of flexible cable ,and as PCB receptacles.
