Wireless charging receiving coil delivers high efficiency for 10-W applications

Vishay Intertechnology, Inc. (Malvern, PA) announced a new powdered-iron-based, WPC-compliant (Wireless Power Consortium) wireless charging receiving coil designed for 10-W applications. Offering a durable construction and high permeability shielding, the new Vishay Dale IWAS-4832FE-50 is said to provide high efficiency greater than 70 percent for wireless charging up to 10 W for portable electronics, including tablets, notebook computers, and handheld medical equipment. The IWAS-4832FE-50's high-saturation powdered iron is not affected by permanent locating magnets, and the device blocks charging flux from sensitive components and batteries. As an alternative to ferrite-based solutions, which can saturate in the presence of a strong magnetic field, the IWAS-4832FE-50 offers a magnetic saturation of <50 percent at 4000 gauss. The RoHS-compliant device features:

• Inductance of 15 µH at 200 kHz with a ± 5 percent inductance tolerance.
• DCR of 255 mΩ at + 25°C.
• Q of 60 minimum at 200 kHz.
• Rated current of 2 A rated current to enable 10 W of charge at 5 V.
