Notes

Output is with the secondary windings connected in parallel.
When ordering, please specify packaging code: e.g. NA5889-ALD
Inductance is for the primary, measured at 50 kHz, 0.1 Vrms, 0 Adc.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance is for the primary and is measured at 50 kHz, 0.1 Vrms, 0 A with secondary windings shorted.
Turns ratio is with the primary and the secondary windings connected in parallel.
1500 Vrms, one minute isolation from primary windings to secondary windings.

Termination:

RoHS-compliant. Tin-silver (96.5/3.5) over tin over copper over steel terminations. Other terminations available at additional cost.

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape (175 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
