Notes
  1. Output of the secondary is with the windings connected in parallel. Bias winding output is 12 V, 20 mA.
  2. When ordering, please specify packaging code: e.g. C1589-ALD
  3. Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc.
  4. DCR for the secondary is per winding.
  5. Leakage inductance measured between pins 3 and 4 with all other pins shorted.
  6. Turns ratio is with the secondary windings connected in parallel.
  7. 1500 Vrms isolation from primary and bias to secondary.

Termination:

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

Packaging:

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