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 andhigh 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 areIWAS3222CZEB190JF1,IWAS3827ABEB110JF1,IWAS4832ABEB110JF1,IWAS4832ADEB150JF1,IWAS4832AAEB220JF1,IWTX4646DCEB240JF1,IWTX47R0DAEB6R3JF1andIWTX47R0EBEB240JF1.
