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. Tin silver over nickel over brass terminations.

Packaging:

  • D = 13″ machine ready reel. EIA-481 embossed plastic tape (200 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
