Vishay Intertechnology Introduces Industry-First Powdered-Iron-Based, WPC-Compliant Rx Coil for Wireless Charging

The Rx coil released today has been designed into a leading wireless power development kit. For wireless power base stations and receivers, the IWAS-4832FF-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-4832FF-50 offers a magnetic saturation of 50 % at 4000 gauss. The RoHS-compliant device features inductance of 9.7 µH at 200 kHz with a ± 5 % inductance tolerance, DCR of 200 mΩ at + 25 ºC, and Q of 30 min. at 200 kHz. The device features a lead length of 50 mm and tinned length of 10 mm.
