Notes
  1. When ordering, please specify packaging code: e.g. B0226-ELD
  2. Inductance is for the primary, measured at 275 kHz, 0.5 Vrms.
  3. Leakage inductance is for the primary winding with the secondary windings shorted.
  4. Isolation (hipot) 1500 Vrms, one minute between the primary and secondary windings.

Termination:

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

Packaging:

  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape (600 parts per full reel).
  • B = Less than full reel
    In tape, not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead.
