Rutronik announces a new powdered-iron-based, WPC-compliant (Wireless Power Consortium) receiving coil for the wireless charging of 5V portable electronics from Vishay.

Optimized for the wireless charging of 5 V portable electronics, Vishay's new IWAS-3827EC-50 powdered-iron-based, WPC-compliant receiving coil provides a durable construction, high permeability shielding, and high efficiency greater than 70 % for Rx applications to 10 W. With dimensions of 38 mm by 27 mm, the device is 33 % smaller than the standard 48 mm by 32 mm IWAS-4832FF-50 Rx coil.

For wireless power base stations and receivers, the IWAS-3827EC-50's high-saturation powdered iron is not affected by permanent locating magnets, and the device blocks charging flux from sensitive components or batteries. As an alternative to Ferrite-based solutions - which can saturate in the presence of a strong magnetic field - the IWAS-3827EC-50 offers a magnetic saturation of 50 % at 4000 gauss. Besides it has an inductance of 10,7 µH at 200 kHz with ± 5% inductance tolerance as well as 183 m? DCR at +25°C. 10mm of 50mm lead length are tinned.

All product information stated in the current press release is based on the franchise situation in Germany. Country specific variations may therefore be possible.
