Notes
  1. When ordering, please specify a packaging code: JA4309-ALD.
  2. Inductance measured on an Agilent/HP 4284 between pins 2 and 4 at 200 kHz, 0.1 Vrms, 0 Adc.
  3. DCR for the secondary is for each winding.
  4. Leakage inductance measured between pins 2 and 4 at 100 kHz, 0.1 Vrms, 0 Adc with all secondary pins shorted.
  5. Primary to secondary.

Termination:

  • RoHS-compliant. 260°C compatible. Matte tin over nickel over brass terminations. Other terminations available at additional cost.

Packaging:

  • 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.
