The W.FL2 Series offers ultra-small surface mount coaxial connectors with a nominal mated height of 1.18mm (max. 1.3mm). These connectors are designed for applications requiring a small board footprint, occupying an area of 3.4mm, and are compatible with the same land pattern as the W.FL Series. They are among the world's smallest and lightest coaxial connectors, with receptacles weighing 5.0mg and right-angle plugs weighing 15.3mg (032) to 17.4mg (040). The series supports a frequency range up to 6 GHz, with a VSWR of 1.3 max. from DC to 3GHz and 1.4 to 1.5 max. from 3GHz to 6GHz depending on cable diameter. Receptacles are packaged on tape-and-reel for automatic board placement. Plugs are terminated with ultra-fine coaxial cables (fluorinated resin insulated) for easy operation in confined spaces. Mating and un-mating are facilitated by dedicated tools. The connectors are halogen-free. They are not designed for environments with excessive fine particles, dust, corrosive gases (sulfur dioxide, hydrogen sulfide, nitrogen dioxide), or large rapid temperature variations.
Suitable for applications demanding compact size and light weight, particularly in mobile devices, medical equipment, and other space-constrained electronic systems.
