  1. When ordering, please specify packaging code: e.g. A0009-ALD
  2. Inductance measured across input and auxiliary windings at 100 kHz, 0.1 Vrms, 0 Adc for one minute.
  3. DCR measured at 25°C. For other operating temperatures,use this DCR at Temperature calculator.
  4. Leakage inductance measured at 100 kHz, 0.1 Vrms from pins 1 to 4 with all other pins shorted.
  5. 500 Vrms, one minute isolation between windings. Isolation measured from pin 1 to pins 5 and 6; from 2 to 5 and 6; and from pins 1, 2, 5 and 6 to the core for one minute.


  • RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations. Other terminations available at additional cost.


  • D = 13″ machine ready reel. EIA-481 embossed plastic tape (150 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.
RoHS compliant
