![]() ![]() 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. You can find more information in our coaxial connectors guide.What do Coaxial Connectors do?Coaxial connectors provide a convenient method of connecting RF equipment together ensuring reliable and efficient signal transmission in a range of electronic devices and systems.ApplicationsCoaxial connectors are used in several applications including:LaboratoryTest and measurementTelecommunicationsBase stationsGPSLANAntennasConsumer electronicsTypes of Coaxial ConnectorsThere are various types of Coaxial connectors available, and each type has its own unique features and can be used in different applications depending on factors such as frequency range, impedance, power handling and evironmental conditions such temperature and humidity.At only 55% of the size of the U.FL connector series, the W.FL Series is one of the world's smallest radio frequency connectors. Coaxial Connectors Coaxial connectors (also known as RF connectors), are electrical connectors used to connect coaxial cables to electronic devices and can carry high-frequency signals over long distances. ![]()
