Characteristics

  • Core material: NiZn
  • Low profile
  • Magnetical shielded which results in a low leakage field
  • 8x8 mm case
  • Operating temperature range -40 up to 125°C
  • 1:1 transformer
  • Low self-losses
  • Higher Self Resonant Frequency
  • Low leakage inductance
  • Coupled inductor with two identical windings
  • Recommended solder profile: Reflow

Applications

  • Non-Isolated Flyback Converter
  • Buck or Boost with auxiliary winding
  • BUCK-BOOST, SEPIC, ZETA & CUK Converter
  • Switching regulators with secound, unregulated output voltage

An Excellent Duet!

The WE-MCRI is an innovative molded coupled inductor with fully automated bifilar winding process. It offers an almost ideal coupling coefficient up to 0.995.
