Notes
  1. When ordering, please specify packaging code: e.g. B0392-ALD
  2. Inductance measured on an Agilent/HP 4284 between pins 1 and 3 at 250 kHz, 0.1 Vrms, 0 Adc.
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. Leakage inductance measured between pins 1 and 3 at 100 kHz, 0.1 Vrms, 0 Adc with secondary pins shorted.
  5. When ordering, please specify packaging code: e.g. B0434-ALD
  6. Inductance measured on an Agilent/HP 4284 between pins 3 and 4 at 250 kHz, 0.1 Vrms.
  7. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  8. Isolation measured from pins 1 to 3.
  9. Isat: DC current at which inductance drops 10% (typ) from its value without current. Details
  10. Irms: Current that causes a 40°C rise from 25°C ambient. Details

Termination:

  • RoHS-compliant. 260°C compatible. Matte tin over nickel over brass terminations.

Packaging:

  • D = 13" machine-ready reel
    EIA 481 embossed plastic tape (200 parts per full reel).
  • B = Less than full reel
    In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead.
