Wirelessly power wearables

The WE-WPCC 760308102212 and the WE-WPCC 760308102213 receiver coils are 0.64mm thin. Featuring broad ferrite projection, the WE-WPCC 760308102212 offers outstanding shielding properties, which is particularly useful in applications that are sensitive to electromagnetic interference. The third receiver coil, WE-WPCC 760308101214, is slightly thicker at 0.8mm, with a diameter of just 19mm.

The selection of the inductance value used in the WE-WPCC 760308102213 product makes it a dual-standard receiver. Fitted with the corresponding receiver chip, the coil is capable of responding to transmitters that are compatible with either the WPC Qi standard or the PMA standard.
Used with the WE-WPCC 760308101104 and the WE-WPCC 760308101105 transmitter coils, the receiver coils achieve outstanding power-transfer results.

To make charging stations that are compatible with these receiver coils, Würth Elektronik has also introduced two wireless power-charging transmitter coils, the WE-WPCC 760308101104 and the WE-WPCC 760308101105. Both coils have an external diameter of just 21mm, and use high-quality ferrite for shielding and stranded wire to keep the RDC to a minimum. The two coils differ in their inductance values.

“Smart watches such as the Motorola 360 and Apple Watch are leading the way, with fitness trackers and other wearables as well as smart phones already in the pipeline. Especially for devices that must be protected against moisture, contact-free recharging has the advantage that the cable socket can be dispensed with,” says Oliver Konz, CEO, Würth Elektronik.

Thomas Schrott, CEO, Würth Elektronik, adds: “We’ve been involved in the Wireless Power Consortium for many years now, actively contributing our competence to drive standardisation further. With our high-quality wireless power products we’re supporting a trend that will in all probability one day enable us to recharge all our mobile devices using one and the same wireless charging unit.”
