X.FL Series, 0.94 mm Mated Height, Supporting up to 12 GHz, Space-saving Ultra Miniature Coaxial Connector

HIROSE Electric Co. Ltd., a world-class manufacturer of innovative connector solutions has released its X.FL coaxial wire-to-board and board-to-board series.

The X.FL ultra-miniature coaxial connector wire-to-board versions offer a low height profile of 0.94 mm (with a variation height of up to 1.3 mm max.), offering high performance to meet requirements of different miniature devices supporting up to 12 GHz and making them ideal for small, hand-held wireless devices.

The X. FL board-to-board version offers a more streamlined solution with vertical mounting to allow a parallel board-to-board or FPC-to-board connection with a low stacking height profile of 0.95 mm max whilst supporting up to 6 GHz. With this compact height profile, X. FL positioning on the PCB is flexible and additionally it enables the accommodation of more components on the same PCB in surrounding space to enhance the application performance and features.

Although Hirose’s X.FL series are miniature connectors with a small mounting space, the frequency characteristics have been dramatically enhanced by reducing the diameter of the male receptacle contact and optimizing the internal design of the plug. Moreover, the applicable cable of ⌀1.13 mm is very thin and flexible, making it easy to route inside devices. The receptacle requires a footprint of only 3.4 mm², which is the same footprint as Hirose’s W. FL and W.FL2 series. In addition, the same land patterns can be used.

The cable mounted plugs use ultra-fine fluorinated resin insulated cable to guarantee secure and stable connection. Different cable diameters are available in single or double-ended cable lengths. Also, with the use of ultra-fine coaxial (fluorinated resin insulated) cables on these connectors offer the ability to complete the connections in small, confined spaces with a smooth, easy operation. This product is available in embossed packaging; this allows the plug and receptacles to be automatically mounted.

Although compact and lightweight the X.FL can handle high transmission speeds which is suitable for a wide range of miniature devices using wireless communication modules, wireless LAN, GPS and Bluetooth.
