Notes
  1. Output of the secondary is with the windings connected in parallel. Bias winding output is 10 V.
  2. When ordering, please specify packaging code: e.g. C1453-ALD
  3. Inductance is for the primary, measured at 250 kHz, 0.3 Vrms.
  4. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  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 primary to secondary isolation; 500 Vrms primary to bias isolation.

Termination:

  • RoHS-compliant. 260°C compatible. Tin-silver (96.5/3.5) over tin over nickel over phos bronze terminations. Other terminations available at additional cost.

Packaging:

  • D = 13" machine-ready reel
    EIA 481 embossed plastic tape (500 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.
