Notes
  1. When ordering, please specify packaging code: e.g. B0853-ALD
  2. Inductance measured on an Agilent/HP 4284 between pins 3 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 measure between pins 3 and 4 at 100 kHz, 0.1 Vrms, 0 Adc with pins 6 and 10 shorted.
  5. Turns ratio is with the secondary windings connected in series.
  6. 1500 Vrms isolation, primary to secondary windings.

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). 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.
