Notes

When ordering, please specify packaging code: e.g. CR8076-ALD
Inductance is for the primary, measured at 250 kHz, 0.1 Vrms.
Isolation is from primary to secondary, tested for one minute.

Termination:

RoHS matte tin over nickel over phos bronze.

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.
