Wurth Electronics is using the latest technology to achieve better results in testing and their quality control. This is a clip of a shielded power inductor from the WE-SPC series from Würth Elektronik taken by a computer tomograph.
The Wireless Power Consortium introduces the Qi Standard for wireless charging! The basic principle of an inductively coupled power transfer system consists of a transmitter coil and a receiver coil. Both coils form a system of magnetically coupled inductors. An alternating current in the transmitter coil generates a magnetic field which induces a voltage in the receiver coil. This voltage can be used to power a mobile device or charge a battery.
