Dual Winding, Shielded Drum Inductors

  • Dual winding inductors that can be used as either a single inductor, or in coupled inductor/transformer applications (1:1 turns ratio)
  • Windings can be connected in series or parallel, offering a broad range of inductance and current ratings
  • Surface mount
  • 200Vac isolation between windings
  • Ferrite core material

Applications

  • Inductor Mode: buck, boost, and coupled inductor
  • Transformer Mode: SEPIC and flyback
  • DC-DC converters
  • VRM inductor for CPU and DDR power supplies
  • Input and output filter chokes
