Notes

Output is with both windings of the secondary connected in parallel.
When ordering, please specify packaging code: e.g. A9967-ALD
Inductance is per winding of the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc. Inductance of the primary, with three windings connected in series is 90 µH.
Leakage inductance is for one winding and is measured with all other windings shorted.
500 Vrms, one minute isolation between windings.

Termination:

RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze. 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.
