Vishay Intertechnology Introduces Industry-First Powdered-Iron-Based, WPC-Compliant Rx Coil for Wireless Charging
New Receiving Coil Works With or Without Alignment Magnet, Offers High Permeability Shielding and Efficiency Greater Than 70 %
(firmenpresse) - MALVERN, PA -- (Marketwire) -- 09/29/11 -- Vishay Intertechnology, Inc. (NYSE: VSH) today announced the industry's first commercially available powdered-iron-based, WPC (Wireless Power Consortium)-compliant wireless charging receiving coil optimized for use with or without an alignment magnet. Offering a durable construction and high permeability shielding, the new IWAS-4832FF-50 provides high efficiency greater than 70 % for the wireless charging of ? 5 W portable electronics.
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 microhenries at 200 kHz with a 5 % inductance tolerance, DCR of 200 milliohms at + 25 degrees C, and Q of 30 min. at 200 kHz. The device features a lead length of 50 mm and tinned length of 10 mm.
Samples and production quantities of the IWAS-4832FF-50 Rx coil are available now, with lead times of five to eight weeks. Follow Vishay at .
