The Hirose U.FL Series is a line of lightweight, SMT micro coaxial connectors designed for space-saving applications. Featuring a low mated height ranging from 1.9mm to 2.4mm, these connectors are ideal for compact electronic devices. The series offers both soldered and solderless connection types, with the U.FL(A) variant supporting frequencies up to 18 GHz. They are suitable for automatic mounting and provide a clear, tactile lock. Applications include wireless LAN equipment (Wi-Fi 6 compatible), Bluetooth devices, car navigation systems, drones, PDAs, GPS, wireless communication devices, and electronic measuring instruments.
