Notes

When ordering, please specify packaging code: e.g. NA6252-ALD
Inductance is for the primary, measured at 150 kHz, 0.1 Vrms, 0 Adc.
Peak primary current drawn at minimum input voltage.
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.
Leakage inductance is for both windings of the primary, measured with the secondary windings shorted.
Turns ratios are with the primary windings connected in parallel.
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.
