Notes
  1. When ordering, please specify packaging code: e.g. NA6252-ALD
  2. Peak primary current drawn at minimum input voltage.
  3. DCR for the primary is with the windings connected in parallel, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. Inductance is for the primary, measured at 150 kHz, 0.1 Vrms, 0 Ad.
  5. Turns ratios are with the primary windings connected in parallel.
  6. 1500 Vrms, one minute isolation from primary to secondary windings.

Termination:

  • RoHS-compliant. Tin-silver (96.5/3.5) over tin over nickel over phos bronze 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.
