1. When ordering, please specify
packaging
code:
FA2707-BLD
Packaging: D
= 13″ machine ready reel. EIA-481 embossed plastic
tape (200 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 for the primary, measured at 250 kHz, 0.2 Vrms.
3. Peak primary current drawn at minimum input voltage.
Dot indicates pin 1
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.
