CHARGING FUNCTION AND NFC COMBINED
Würth Elektronik expands its portfolio of wireless power coils. WE-WPCC WPT/NFC combines wirelesspower transmission with the Near Field Communication (NCF) standard thusenabling, for example, the combination of a charging station forsmartphones with identification and payment functions. Other newadditions to the world’s largest range of wireless power transfer coilsinclude a high power coil (WE-WPCC 760308101311 [10]) with 400 W outputand a “flat” version, two coils whose respective heights of 2.8 mm and3.1 mm are only half as high as those of other transmitter coils(WE-WPCC 760308101411 [11] and 760308101410 [12]).
The NFC coil in the WE-WPCC WPT/NFC enables data rates up to 848 kbps
and the WPT coil allows wireless power transmission output up to 100 W
(at 20 V input voltage) in one efficient solution. Data can be
transferred while wirelessly charging sensors, smartphones, wearables,
handhelds, digital cameras, smart watches or tablets. The coil
combination in the compact PET sleeve with adhesive surface can be used
according to the Qi (5 W and 15 W) and AirFuel Alliance standards as
well as in proprietary solutions with higher power. This means the
transmitter is equally suitable for consumer electronics and industrial
applications. Stranded wire and high-quality ferrite material ensure
maximum energy transmission efficiency and the high permeability of the
shielding concentrates the magnetic field and protects sensitive
electronics or batteries from interference signals.
For the optimal combination of transmitter and receiver coils, Würth
Elektronik recommends its “Mix and Match [13]” tool and also the
Wireless Power Development Kits [14].
The new transmitter coils are now available from stock without a minimum
order quantity. Free samples can be requested.
