Qi Wireless Charging Rx and Tx Charging Coils for High Efficiency Portable Electronics
Vishay Intertechnology has introduced new powered iron-based, WPC (Wireless Power Consortium)-compliant wireless charging coils to replace the devices for which end-of-life (EOL) has announced in 2017. The new coils are designed in a variety of industry-standard sizes with durable construction and high permeability along with high efficiency. The coils are available with heat rated current of 6 A and 7 A, and saturation current of 20 A and 22 A.
Today, the company announced the release of six new receiver coils and three new transmitter coils. The part number of the coils are IWAS3222CZEB190JF1, IWAS3827ABEB110JF1, IWAS4832ABEB110JF1, IWAS4832ADEB150JF1, IWAS4832AAEB220JF1, IWTX4646DCEB240JF1, IWTX47R0DAEB6R3JF1 and IWTX47R0EBEB240JF1.
