注释
  1. When ordering, please specify packaging code: e.g. DA2420-ALD
  2. Inductance is for the primary, measured at 100 kHz, 0.1 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 windings with all secondary pins shorted.
  5. Turns ratio is with the primary windings connected in parallel.
  6. 500 Vdc isolation from primary to secondary.

端子:

  • RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations.

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.
