Notes
  1. When ordering, please specify packaging code: e.g. C1539-ALD
  2. Inductance measured on an Agilent/HP 4284 between pins 2 and 4 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 2 and 4 at 100 kHz, 0.1Vrms, 0 Adc with pins7 and 9 shorted.
  5. 1500 Vdc isolation, primary to secondary.

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.
