wuerth0214Würth Elektronik extends its wireless power coil range with three transmitter coils and one receiver coil. The new 760 308 100 110 10 (A760) and 308 100 111 11 (AXNUMX) round transmitter coils comply with the Qi standard of the Wireless Power Consortium (WPC). The pot shape of the ferrite core bundles tightly, increases the possible coil spacing and reduces radiation to the outside. The round shape also reduces the required installation space considerably.

For small receiver coils and smaller transmitter coils are required, since the area ratio of transmitting and receiving coil significantly enters into the efficiency of energy transfer. In order to offer a transmitter solution for the market of small receivers such as sensors, wearables, hearing aids, etc., the 760 308 101 103 has been developed. With this compact transmitter coil can be up to 5 W transferred and it also corresponds to the Qi standard of the WPC. With a diameter of 30 mm, it has only about one third of the area of, for example, the coil 760 308 100 111.

Today, there are two inductive wireless power standards; the Qi standard of the WPC and the PMA standard of the Power Matter Alliance. The manufacturer offers a dual standard receiver coil 760 308 102 210. Devices equipped with this high-quality coil with stranded wire and ferrite reinforcement in the middle can be operated on charging stations of both standards.
