The TE Connectivity 1055689-1 is an OSMT-style RF receptacle with a male pin centre contact, designed for surface-mount microstrip applications. This 50 Ohm connector is rated to 6 GHz maximum frequency, making it suited for compact wireless modules, GPS receivers, and IoT radio boards where board space is tight and a low-profile RF interconnect is needed. The snap-on fastening gives a positive retention without requiring a threaded coupling nut — quick to mate in production, but the 100 mating cycle rating means it's not intended for frequent field disconnect cycles.
RF and electrical ratings
The 6 GHz upper frequency covers common ISM bands and GPS without issue. Voltage rating is 250 V.
Mechanical and environmental
The dielectric is polyphenylene sulfide (PPS), a high-temperature thermoplastic that holds up to reflow soldering without dimensional shift. Surface-mount mounting with solder shield termination keeps the assembly clean for automated pick-and-place.
