Vishay announced a commercially available powdered-iron-based, WPC (Wireless Power Consortium)-compliant wireless charging receiving coil optimised for use with or without an alignment magnet.
Offering a durable construction and high permeability shielding, the new IWAS-4832FF-50 provides efficiency greater than 70% for the wireless charging of 5 W portable electronics.
The Rx coil 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°C, and Q of 30 minimum at 200 kHz. The device features a lead length of 50 mm and tinned length of 10 mm.
