注释
  1. When ordering, please specify packaging code: e.g. DA2383-ALD
  2. Inductance is for the primary, measured at 200 kHz, 0.2 Vrms, 0 Adc.
  3. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. Leakage inductance measured on the primary winding with all secondary pins shorted.
  5. 1500 Vrms, one minuteisolation from primary and aux to secondary.

端子:

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

包装:

  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape (175 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.
