1. When ordering, please specify a

packaging

code:

FA2898-ALD

Packaging: D

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

tape (175 per full reel).

= 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 for the primary, measured at 250 kHz, 0.7 Vrms, 0 Adc.

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.

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.

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

Pri

Aux

Sec

The primary windings and the secondary

windings are to be connected in parallel

on the PC board.

Dimensions are in

inches
