Vishay launches wireless charging A11 Type Tx Coil for 5 V applications

Latest Electronics ProductsVishay Intertechnology has introduced a new powdered-iron-based, WPC-compatible (Wireless Power Consortium) wireless charging A11 type transmitter coil for 5 V applications. AEC-Q200 qualification is pending. Offering a durable construction and high permeability shielding, the new Vishay Dale IWTX-47R0BE-11 6.3 μH is 18 % smaller than other solutions on the market to save space in Qi wireless charging pads, while providing high efficiency greater than 70 % when paired with a Vishay Rx coil and appropriate Qi-compatible Rx and Tx circuitry.

Designed for use in conjunction with Vishay’s WPC-compatible wireless receiver coils, the IWTX-47R0BE-11 6.3 μH’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 6.3 μH offers a magnetic saturation of 50 % at 4,000 gauss.

The RoHS-compliant device features low inductance of 6.3 µH at 200 kHz with a + 5 % inductance tolerance, DCR of 38 mΩ (± 10 %) at + 25 °C, and Q of 190 typical at 200 kHz. The transmitter coil features a lead length of 47 mm and tinned length of 5 mm, and self-resonant frequency of 22 MHz.

Samples and production quantities of the IWTX-47R0BE-11 6.3 μH Tx coil are available now, with lead times of 14 weeks for large orders.
