Wireless Charging Transmitter Coil Offers Small Size and High Efficiency
IWTX-47R0BE-11 AEC-Q200-Qualified Wireless Charging Transmitter Coil Offers Small Size and High Efficiency for Qi Wireless Charging Pads
Vishay Intertechnology introduces a new AEC-Q200-qualified, powdered-iron-based, WPC-compliant (Wireless Power Consortium) wireless charging transmitter coil for Qi wireless charging pads. 18 % smaller than previous-generation solutions to save space. Designed for use in conjunction with Vishay’s WPC-compliant wireless receiver coils. High-saturation powdered iron is not affected by permanent locating magnets. Provides an alternative to larger ferrite-based solutions, which can saturate in the presence of a strong magnetic field.
The Key Specifications:
- Efficiency > 70 %
- 50 % magnetic saturation at 4,000 gauss
- 24 μH inductance at 200 kHz, +5 % / -10 % inductance tolerance
- DCR of 71 mΩ (± 10 %) at +25 ºC
- Q of 200 typical at 200 kHz
- 40 mm lead length, 5 mm tinned length
- 6 A heat rated current, 20 A saturation current
- 7 MHz self resonant frequency
Product Benefits:
- AEC-Q200-qualified
- WPC-compliant
- Durable construction
- High permeability shielding
- Provides high efficiency greater than 70 %
- RoHS-compliant
Partnumber:
IWTX47R0BEEB240K11
