U.FL connectors are commonly used in applications where space is of critical concern, such as in smartphones and laptop Wi-Fi cards.

The female U.FL connectors are generally not sold separately, but rather as part of a pigtail with a high-quality 1.32 mm doubly shielded cable, which allows for a low-loss connection, insulated with fluorinated resin.

The male connectors are surface-mounted (SMT) and soldered directly to the printed circuit board (PCB).

The Hirose W.FL, also known as Amphenol AMMC,[9] is an ultra-small RF connector used in handheld electronic products.
