The gold-plated brass body and center contact resist corrosion across the -55°C to 155°C operating range, while the PTFE dielectric keeps the impedance stable through temperature swings.
This part is listed as Obsolete. There is no official successor order code, so the replacement path is a form-fit-function cross to another MMCX plug at 50 Ohm with the same snap-on interface.
The through-hole solder termination suits board-level mounting where the centre pin and shield are soldered directly to the PCB. The single-port configuration is straightforward — one RF channel per connector. Gold finish on both the body and the centre contact is standard for MMCX interfaces, giving consistent contact resistance over the rated mating cycles.
