UFL series ultra small and lightweight SMT coaxial receptacle connectors with a space saving PCB footprint of 7.7 mm² and weighing just 15.7 mg. These UFL receptacles have a high frequency performance from DC to 6 GHz with a VSWR of 1.3 to 1.5 maximum. This performance makes them ideal for use in a wide range of miniature devices. Supplied on tape and reel, these receptacles can be positioned using automatic placement equipment. When mated with the UFL plug assemblies a tactile click is produced that confirms that a secure electrical and mechanical connection has been made. A range of mated heights from 1.9 mm to 2.4 mm are possible when using this UFL receptacle with the UFL plugs.
