Wireless charging transmitter coils and shields provider high efficiency

Vishay-Dale IWTX wireless charging transmitter coils and shields, available from Mouser, offer a durable construction and high permeability shielding. The devices high-saturation powdered iron is not affected by permanent locating magnets. As an alternative to larger Ferrite-based solutions - which can saturate in the presence of a strong magnetic field - the IWTX-4646BE-50 offers a magnetic saturation of 50% at 4000 gauss. The IWTX-47R0BE-11 offers a permeability of ~24 and a resistivity of >10Mohm at 100V. WPC compatible and Qi wireless charging pads are typical applications.
