Würth Elektronik expands its attractive Wireless Power Coil program with three transmitter coils and one receiver coil. The new round transmitter coils 760 308 100 110 (A10) and 760 308 100 111 (A11) comply with the Qi standard of the Wireless Power Consortium (WPC). The ferrite pot core shape has the major advantages of tightly bundling the magnetic field, increasing the possible coil distance and reducing outward radiation. The round shape also significantly reduces the mounting space required.

For small receiver coils, smaller transmitter coils are also necessary, as the area ratio between transmitter and receiver coil significantly affects the efficiency of energy transmission. In order to offer a transmitter solution for the market of small receivers (sensors, wearables, hearing aids, etc.), 760 308 101 103 was developed. This compact transmitter coil transfers up to 5W and it also complies with the WPC Qi standard. With a diameter of 30 mm, its area is only around a third of coil 760 308 100 111, for example.

Today there are two inductive wireless power standards: the Qi standard of the WPC and the PMA standard of the Power Matters Alliance. Würth Elektronik offers a dual standard receiver coil – 760 308 102 210 – for this purpose. The advantage of this high quality coil with litz wire and ferrite fortification in the center is that devices using this solution can be charged on charging stations of both standards. With this intelligent expansion of the product spectrum, Würth Elektronik demonstrates its competence in the field of wireless power technology.

All new coils are immediately available from stock.
