Murata Manufacturing has introduced a winding power inductor for wearable devices that achieves a large L (22µH) despite its low 0.5mm profile.

There is an increasing demand for compact, low-profile power inductors in electronic devices such as wearable devices and smart cards. Because liquid crystal panels are mounted on these devices, inductors that have both a low profile as well as a high L value are needed for the panel drivers. Yet in the conventional monolithic type low-profile high-power inductors LQM_CH series, the L value was limited to 2.5µH.

Murata's 2.5mm x 2mm winding inductors from the LQH2HPN_DR series are intended for wearable devices. It is available in a variety of L values up to 22µH.
