  MALVERN, PA, Sep 29 (MARKET WIRE) -- 
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
