The 75 Ohm impedance targets video distribution, broadcast, and telecom RF paths where 50 Ohm would mismatch the line. The white bronze body finish on a brass shell gives a corrosion-resistant mating surface that holds up to 500 mating cycles — suited for test equipment, panel jacks, or field-serviceable radio ports where the connector sees repeated connect-disconnect. ## Mating and Termination — What Connects Where This jack mates with any standard 75 Ohm MCX plug that uses a snap-on latch — the female socket accepts the male centre pin, and the outer shell snaps over the plug body. No BNC or SMA compatibility: MCX is a separate interface with a smaller 2.54 mm (0.100 in) outer conductor diameter. Termination is through-hole solder for the centre contact and shield. No crimp, no clamp — a soldered joint for permanent or semi-permanent installation.","metaTitle":"919-124J-71P MCX Jack, 75 Ohm, 6 GHz, Through Hole, Snap-On","metaDescription":"919-124J-71P MCX jack, female socket, 75 Ohm impedance, rated to 6 GHz.
