注释
  1. When ordering, please specify packaging code: e.g. WA8417-ALD
  2. Inductance is for the primary, measured on an Agilent/HP 4284 at 400 kHz, 0.6 Vrms, 0 Adc.
  3. Isat: DC current that causes an inductance drop of 30% (typ) from its value without current.
  4. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  5. Leakage inductance measured between pins 3 and 4 at 400 kHz, 0.6 Vrms, 0 Adc with pins 10 and 9 shorted.
  6. 2500 Vrms, one minute isolation from primary to secondary.

端子:

  • RoHS tin-silver-copper (95.5/3.8/0.7) over tin over nickel over phos bronze.

包装:

  • D = 13" machine-ready reel
    EIA 481 embossed plastic tape (600 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.
