Notes

Output for the secondary is between pins 7 and 10. Bias winding output is 10 V, 20 mA. Sync winding output is a 5 V Sync FET gate drive signal.
When ordering, please specify packaging code: e.g. NA6223-ALD
Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc.
Ipk is the peak primary current drawn at minimum input voltage.
DCR for the primary is from pin 1 to pin 2, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance if for the primary and is measured with all other windings shorted.
Turns ratio is with the primary windings connected in series.
1500 Vrms, one minute isolation from the primary and bias windings to the secondary.

Termination:

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

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.
