1. When ordering, please specify a packaging code:

FA2898-ALD

3. Ipk is the peak current drawn at minimum input voltage.

4. DCR for the primary and the secondary is with windings connected in

parallel.

5. Leakage inductance measured on the primary windings with all sec-

ondary pins shorted.

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

tape (175 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.

6. Turns ratios are with the primary windings and the secondary windings

connected in parallel.

7. Output is with the secondary windings connected in parallel.

8. Electrical speciﬁcations at 25°C.

2. Inductance is for the primary, measured at 250 kHz, 0.7 Vrms, 0 Adc.

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