Low-profile dual winding shielded drum inductor/transformer Product features

  • 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
  • Current range from 0.063 A to 6.43 A
  • Inductance range from 0.47 µH to 4.03 mH
  • Ferrite shielded, low EMI
  • Ferrite core material
  • 500 Vdc isolation between windings

Applications

  • Transformer: (1:1), SEPIC, flyback
  • Buck, boost, coupled inductor
  • Mobile phones
  • Notebook and laptop power
  • Digital cameras
  • Media players
  • PCMCIA cards

It is recommended that the temperature of the part not to exceed +125 °C. Derating is necessary for AC currents (3) Isat: Peak current for approximately 30% rolloff @ +20 ° C (4) DCR limits @ +20 °C (5) Applied Volt-Time product (V-µs) across the inductor at 100 kHz necessary to generate a core loss equal to 10% of the total losses for a 40 °C temperature rise. Derating of the Irms is required to prevent excessive temperature rise.
