Vishay Intertechnology Wireless Charging A11 Type Tx Coil for 5 V Applications Saves Space in Qi-Compatible Wireless Charging...
June 29 2016 - 11:00AM
Vishay Intertechnology, Inc. (NYSE:VSH) today 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.
