Notes
  1. When ordering, please specify a packaging code: HA3648-BLD
  2. Inductance measured on an Agilent/HP 4284 between pins 3 and 4 at 250 kHz, 0.1 Vrms, 0 Adc.
  3. DCR for the secondary is from pin 6 to pin 10.
  4. Leakage inductance measured between pins 3 and 4 at 250 kHz, 0.1Vrms, 0 Adc with pins 6, 8 and 10 shorted.
  5. 1500 Vdc isolation, 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.
