The gold-plated brass body and beryllium copper center contact with gold plating deliver 500 mating cycles — enough for field-service disconnect without the wear of a daily-use test port. The PTFE dielectric maintains consistent impedance through the interface. ## 2 GHz Ceiling vs 6 GHz Sibling — Pick the Bandwidth You Need The 919-118J-51P is specced to 2 GHz, while the functionally similar 919-382J-51P carries a 6 GHz rating at the same 50 Ohm impedance. Both share the MCX snap-on interface, gold body finish, 500 mating cycles, and SMT shield termination. The difference is the frequency headroom: the 919-382J-51P covers wider-band signals (e.g., higher-order harmonics or multi-band radios), while the 919-118J-51P is a cost-appropriate fit for sub-2 GHz applications like GPS, ISM-band radios, or baseband I/O. The 919-384J-51PT is the tape-and-reel variant of the 6 GHz part for high-volume lines. No other functional difference — same footprint, same mating half.","metaTitle":"919-118J-51P MCX Receptacle, 50 Ohm, 2 GHz, SMT, Gold","metaDescription":"919-118J-51P MCX receptacle, 50 Ohm, 2 GHz max, SMT, gold body, 500 mating cycles.
