The Hirose U.FL-PR-SMT2.5-1(10) is a surface-mount plug with a female socket interface, part of the U.FL series of ultra-miniature coaxial connectors. The gold-plated phosphor bronze body and gold centre contact resist corrosion in indoor environments, and the snap-on fastening gives a quick positive mate without tools.
Why the 10 Mating Cycles Matter for Your Build
The 10 mating cycles on this U.FL plug is the spec that decides its role. Compare it to the U.FL-R-SMT-1(40) receptacle, which carries 30 mating cycles — triple the reconnect life. If your design requires field-service disconnect or repeated testing, step up to the 30-cycle receptacle variant.
This is a surface-mount part — the shield and centre contact both terminate via solder to the PCB pads. The shield termination is solder, and the contact termination is solder, so there is no crimp or through-hole work. The snap-on fastening means the mating receptacle (a U.FL-R-SMT series part) simply pushes on and locks with an audible click. The liquid crystal polymer (LCP) dielectric handles the reflow temperatures without issue. For the board layout engineer: the SMT footprint is compact, but the 50 Ohm impedance path depends on matching the trace width and ground-plane clearance to the connector launch — treat it like any other RF launch point.
