Wireless charging receiving coil operates with or without alignment magnet
Offering a durable construction and high permeability shielding, the new IWAS-4832EC-50 provides high efficiency greater than 75% for the wireless charging of 7 V portable electronics.
The Vishay Dale Rx coil has been designed into a leading wireless power development kit. For higher voltage wireless power base stations and receivers, the IWAS-4832EC-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-4832EC-50 has magnetic saturation of 50% of inductance at 4000 gauss. The RoHS-compliant device features inductance of 16.2 μH at 200 kHz with a ± 5 % inductance tolerance, DCR of 366 mΩ at + 25 °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-4832EC-50 Rx coil are available now, with lead times of stock to six weeks.
