Ultra-Thin Receiving Coil Unit

TDK Corporation's wireless power transfer coil unit is designed for smartphones and other mobile devices. The receiving coil is designed for integration in smartphones, representing an industry-leading achievement, featuring a mere 0.57 mm thickness.

The coil unit not only is ultra-thin and lightweight, it is also highly resistant to shock and therefore provides excellent reliability. Furthermore, in spite of its 0.57 mm profile, the coil's design minimizes the tendency towards rising resistance and achieves a power transfer efficiency that allows clearing the requirements of the WPC "Qi" standard. The low height of the unit is a key aspect for use in smartphones.
