Characteristics

  • Composite core material allows high saturation current and compact design
  • Better Leakage Inductance (Lk) and Rated Current (Ir) than comparable components
  • Magnetically shielded
  • 1:1 Transformer
  • Operation temperature: -40°C to +125°C

Applications

  • Isolated converter application (e.g. Flyback converter)
  • Buck, Boost, Sepic, Zeta, CUK Converter
  • Switching regulator with second, 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.
