These E&E coils are compliant with the Qi interface-standard specifications, which have been developed by the Wireless Power Consortium (WPC). The Qi standard enables inductive electrical power transfer over distances of up to 4 cm. The Qi standard enables design freedom, product differentiation and guaranteed wireless-charging interoperability.
Two new ranges of transmitter and receiver coil modules are available offering 5W low-power transfer and the 15W medium-power extension to the WPC standard. Available in various operating temperature ranges, these modules exhibit low resistance and low temperature rise on operation. Various magnetic inductance version are available, in addition to various coil shapes and dimensions available for custom designs.
