MALVERN, Pa., March 22, 2016 -- Vishay Intertechnology, Inc. (NYSE:VSH) today 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 new Vishay Dale 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 19 V input for up to 10 W 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 24 µH at 200 kHz with a +5 % / -10 % inductance tolerance, DCR of 71 mΩ (± 10 %) at + 25 °C, and Q of 200 typical at 200 kHz. The transmitter coil features a lead length of 40 mm and tinned length of 5 mm, and self-resonant frequency of 7 MHz.
Samples and production quantities of the IWTX-47R0BE-11 Tx coil are available now, with lead times of 14 weeks for large orders.
Vishay Intertechnology, Inc., a Fortune 1000 Company listed on the NYSE (VSH), is one of the world's largest manufacturers of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors).
