W.FL cables can only be made with the very thin and flexible coaxes such as 1.13 or thinner. Insulation resistance: The insulation resistance is 500 megohms.Contact resistance: At the center contact the resistance is 20 megohms max.1.3 max (up to 3 GHz) 1.4 max (3 GHz to 6 GHz) Frequency range: The W.FL connector is a microwave connector that has a frequency range of DC to 6 GHz.Impedance: The W.FL connector has a nominal impedance of 50 Ohm.The W.FL connector is minute and fragile and cannot withstand repeated connection and disconnection. The W.FL receptacles are supplied on a tape and reel and can be located on a PCB using the vacuum nozzles of the automatic placement equipment. The center contact is male and is surrounded by a liquid crystal polymer dielectric. Its shell is made from silver-plated phosphor bronze and its inner connector pin is made from brass. The PCB-mounted W.FL receptacle has dimensions of 2 mm (length) by 2mm (width) and a height of 0.85 mm. It uses ultra-fine, fluorinated resin-insulated coaxial cable, as it facilitates using the connector in compact and confined environments. W.FL plugs are always supplied as cable assemblies. Within the connector, there is a small amount of polybutylene terephthalate (PBT), a semi-crystalline engineering thermoplastic, as a dielectric material. The shell of the plug is made from silver-coated phosphor bronze and the inner receptacle is made from gold-plated phosphor bronze. It dimensions are 2.12 mm (width) by 1.38 mm (height) by 3.65 mm (length). The W.FL plug has a right-angle orientation. Its mated weight is 5.6mg for the receptacle and 18.6 mg for the plug. The W.FL connector has a mated height of 1.4 mm (max 1.55mm). W.FL plugs are terminated only using ultra-fine coaxial cables with fluorinated resin (Teflon) insulation. W.FL connectors feature a user-friendly tactile click when successfully coupled. This is best done with a special mating and unmuting tool that ensures that the connector is properly connected and disconnected. The male being placed directly on top of the female connector mates them. The W.FL comprises a female plug connector and a male jack with surface mount technology (SMT) that can be mounted directly onto a circuit board. Physical specifications of the W.FL connector The scaling down of the W.FL connector achieves a massive reduction in the board space occupied by the connector. It is used in printed circuit boards PCBs with its jack being board-mounted. The W.FL connector is in many aspects a smaller version of the Hirose U.FL connector, a standard in the wireless networking industry due to its extremely small mounting area. Termination is done using specialized tools. W.FL plugs are terminated only using ultra-fine coaxial cables with fluorinated resin insulation. W.FL connectors feature a user friendly tactile click when successfully coupled. W.FL occupies a mounting area of 3.4 mm square and is extremely lightweight, with a fully mated height of only 1.4mm. The connector has a frequency range of 0 - 6 GHz from DC and an impedance of 50 Ohms. It is also known as an Ultra Small Surface Mount Coaxial Connector.
W.FL is a Micro-Miniature, lightweight coaxial connector made by Hirose Electric Group, a Japanese electronics company. This short guide provides you with the essentials of W.FL connectors and cables and their common applications.
This micro-miniature connector produced by Hirose is a space-saving solution for introducing wireless connectivity into densely packed electronic circuits.
