1. When ordering, please specify packaging code:
C1174-ALD
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 100 kHz, 0.1 Vrms.
3. Peak primary current drawn at minimum input voltage.
4. DCR for secondary is with windings connected in parallel.
5. Leakage inductance for the primary is with the secondary and drive
windings shorted; leakage inductance for the drive winding is with the
secondary windings shorted.
6. Turns ratio is with both secondary windings connected in parallel.
7. Output of the secondary is with the windings connected in parallel. Bias
winding output is 10 V, 20 mA.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
