WRSR Series

Share

Signal’s Wireless Rectangular Charging Coil (WRSR) Series are receiving rectangular wireless charging transmission coils, available in single windings configuration. The WRSR Series allows power to be transmitted wirelessly through inductive coupling to charge an array of products. The WRSR Series transmitter coils utilize inductive coupling to transfer signals, data and power from one source to another. The advantages of the WRSR’s use of inductive coupling eliminates conductive connections and traditional wiring, seamlessly transferring data and power while avoiding the mechanical abrasion, corrosion and wearing- out of conductive contacts. The fixed-in position inductive coils are non-moving, resistant to vibration and corrosion, and are designed for reliability and longevity.

Specifications

  • Impedance range: 11 to 16.7 ohms at 125 kHz
  • I sat range: 4.0 to 6.0 A
  • Operating Temperature: -25 °C to +105 °C
  • Storage Temperature: -40 °C to +85 °C

Features

  • Single coil, four layers
  • Inductance tolerance: Rectangular core shape
  • Size and shape characteristics are customizable
  • Low profile & high mechanical intensity
  • Qi standard compliance
  • RoHS and REACH compliant
  • Pin cooling technology and tight pin tolerance control within ±1.0 mm after the tin immersion process
