Notes
  1. Output is with the secondary windings connected in parallel.
  2. When ordering, please specify packaging code: e.g. CX9649-ALD
  3. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc
  4. DCR for the secondary is with both windings connected in parallel.
  5. Leakage inductance measured between pins 1 and 3 with all other pins shorted.
  6. Turns ratio is with the secondary windings connected in parallel.
  7. 1500 Vrms, 5 mA, one minute isolation (hipot) between primary and auxiliary to secondary.

Termination:

  • RoHS-compliant. 260°C compatible. RoHS tin-silver-copper (95.5/3.8/0.7) over tin over nickel over phos bronze terminations.

Packaging:

  • 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.
