注释
  1. Output is with the secondary windings connected in parallel. Output of the bias winding with a 15 V, 0.2 A
  2. When ordering, please specify packaging code: e.g. C1048-ALD
  3. Inductance is for the primary, measured at 250 kHz, 0.3 Vrms, 0 Adc.
  4. DCR is for both windings of the secondary connected in parallel.
  5. Leakage inductance is for the primary winding with the secondary windings shorted.
  6. Turns ratio is with the secondary windings connected in parallel
  7. 1500 Vrms, one minute primary to secondary isolation.

端子:

  • RoHS tin-silver (96.5/3.5) over tin over nickel over phos bronze. Other terminations available at additional cost.

包装:

  • D = 13" machine-ready reel
    EIA 481 embossed plastic tape (200 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.
