1. When ordering, please specify a packaging code:

RA6999-ALD

Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic tape (175 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.

2. Inductance is measured at 250 kHz, 0.1 Vrms.

3. Output is for the secondary winding. Output of the gate winding is 12 V, 0.25 A

4. Electrical speciﬁcations at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
