The snap-on fastening provides a quick, secure mate without threads, but the 30-cycle mating life means this connector is intended for limited reconnection — think factory-calibrated assemblies or module-to-antenna links that mate once and stay put.
Surface-mount termination with the shield soldered directly to the board ground plane — the SMT footprint keeps the RF return path short and the impedance controlled through the launch.
What the 30-Cycle Mating Life Means
Thirty mating cycles is low for a coaxial connector — typical U.FL parts are rated 30 to 50 cycles. This is not a connector for frequent disconnect/reconnect in test or field-service scenarios. If your application requires more than a handful of mates over the product life, this is the wrong part.
