Vishay Intertechnology Introduces New Powdered-Iron-Based, WPC-Compliant Rx Coil for 5 V Wireless Charging Circuitry
New Device Features High Permeability Shielding and Efficiency Greater Than 70 %
(firmenpresse) - MALVERN, PA -- (Marketwire) -- 07/12/12 -- Vishay Intertechnology, Inc. (NYSE: VSH) today announced a new powdered-iron-based, WPC-compliant (Wireless Power Consortium) receiving coil for the wireless charging of 5 V portable electronics. Offering a durable construction and high permeability shielding, the new IWAS-3827EC-50 provides high efficiency greater than 70 % for Rx applications to 10 W and is 33 % smaller than the standard 48 mm by 32 mm IWAS-4832FF-50 Rx coil, with dimensions of 38 mm by 27 mm.
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 shields sensitive components or batteries from charging flux. 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.
The RoHS-compliant device features inductance of 10.7 microhenries at 200 kHz with a 5 % inductance tolerance, DCR of 183 milliohms at + 25 ºC, and Q of 30 typical at 200 kHz. The receiving coil features a lead length of 50 mm and tinned length of 10 mm.
Samples and production quantities of the IWAS-3827EC-50 Rx coil are available now, with lead times of five to eight weeks. Follow solutions from Vishay at .
