1. When ordering, please specify

packaging

code:

FA2707-BLD

Packaging: D

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

tape (200 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, 0.2 Vrms.

3. Peak primary current drawn at minimum input voltage.

Dot indicates pin 1

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

parallel.

5. Leakage inductance is for the primary, measured with the secondary

and drive windings shorted.

6. Turns ratio is with the primary and the secondary windings connected in

parallel.

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

Aux winding output is 10 V; drive winding output is 5.5 V.

8. Electrical specifications at 25°C.

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