Coils combine wireless charging with NFC
Würth Elektronik has combined wireless power transmission with the Near Field Communication (NCF) standard, enabling a charging station for smartphones that adds identification and payment functions.
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 100W (at 20V input voltage) in one efficient solution. The coil combination in a compact PET sleeve with adhesive surface can be used according to the Qi (5W and 15W) and AirFuel Alliance standards as well as in proprietary solutions with higher power.
Other new additions include a high power coil (WE-WPCC 760308101311) with 400 W output and a “flat” version, two coils whose respective heights of 2.8 mm and 3.1 mm are only half as high as those of other transmitter coils (WE-WPCC 760308101411 and 760308101410).
For the optimal combination of transmitter and receiver coils, Würth Elektronik recommends its “Mix and Match” tool and also the Wireless Power Development Kits.
