메모
  1. When ordering, please specify packaging code: e.g. DA2257-ALD
  2. Inductance is for the primary, measured at 250 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 is for the primary winding with all other pins shorted.
  5. 2000 Vrmsisolation from primary and aux to secondaries.

종단 처리:

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

패키지:

  • 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.
