Vishay has introduced a new AEC-Q200-qualified, powdered-iron-based, WPC-compliant (Wireless Power Consortium) wireless charging A10 type transmitter coil.
Offering a durable construction and high permeability shielding, the IWTX-47R0BE-11 is 18% smaller than previous-generation solutions to save space in Qi wireless charging pads, while providing high efficiency greater than 80% when paired with a Vishay Rx coil and appropriate Qi-compatible Rx and Tx circuitry. The IWTX-47R0BE-11 is suitable for use in WPC-compatible Tx circuits operating with 19V input for up to 10W wireless charging applications.
Designed for use in conjunction with Vishay's WPC-compliant wireless receiver coils, the IWTX-47R0BE-11's 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-47R0BE-11 offers a magnetic saturation of 50% at 4,000 gauss.
The RoHS-compliant device features inductance of 24µH at 200kHz with a +5% / -10% inductance tolerance, DCR of 71mohm (±10%) at +25C, and Q of 200 typical at 200 kHz. The transmitter coil features a lead length of 40mm and tinned length of 5mm, and self-resonant frequency of 7MHz.
