The TE Connectivity 5-1814832-2 is an SMA jack, female socket, part of the ZDC and Greenpar series. This is a 50 Ohm RF interconnect rated to 6 GHz, with a threaded coupling for secure mated connections. The through-hole mount and solder termination suit it for PCB edge launch or panel mount applications where signal integrity up to 6 GHz is required. The 500 mating cycle rating means this jack is built for repeated connect-disconnect duty in test setups, instrumentation, or field-serviceable equipment — not just a one-time install. The gold-plated beryllium copper center contact keeps contact resistance low across those cycles, and the PTFE dielectric maintains consistent impedance through temperature swings from -65°C to 165°C. The 335 V voltage rating gives headroom for RF power applications where the signal rides on a DC bias or where peak envelope voltages climb. The gold body finish on a zinc alloy shell provides corrosion resistance for indoor or sheltered outdoor use.
Both the center contact and shield terminate via solder — a standard approach for through-hole SMA jacks. The shield termination is soldered directly to the PCB ground plane, which keeps the RF return path short and the launch impedance clean.
