Vishay – New IWTX-4646BE-50 Wireless Charging Transmitter Coil

Vishay Intertechnology, Inc. (NYSE: VSH) announces a new powdered-iron-based, WPC-compliant (Wireless Power Consortium) wireless charging transmitter coil for Qi wireless charging pads.

  • Designed for use in conjunction with Vishay’s WPC-compliant wireless receiver coils
  • Provides an alternative to larger Ferrite-based solutions, which can saturate in the presence of a strong magnetic field  AEC-Q200 certification is pending.

Product Benefits:

  • Powdered iron based
  • Not affected by permanent locating magnets
  • Durable construction
  • High permeability shielding
  • Provides high efficiency greater than 70 % at a 19 V input voltage
  • When tested using WPC-compliant transmitter and receiver chipsets and an IWAS-4832FF-50 receiver coil with 2.7 mm spacing
  • Blocks charging flux from sensitive components or batteries
  • Magnetic saturation of 50 % at 4000 gauss
  • AEC-Q200 automotive certification to be complete in Q1 2015

Applications:

  • WPC compatible and Qi wireless charging pads

Key Device Specifications:

  • Efficiency > 70 %
  • 50 % magnetic saturation at 4000 gauss
  • 24 μH inductance at 200 kHz
  • ± 5 % inductance tolerance
  • DCR of 71 mΩ (± 10 %) at +25 ºC
  • Q of 185 typical at 200 kHz
  • 40 mm lead length
  • 50 mm tinned length of 5 mm
  • 6 A heat rated current
  • 20 A saturation current
  • 7 MHz self resonant frequency
