1. When ordering, please specify packaging code:  
C1174-ALD  
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.  
Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic  
tape (200 per full reel).  
6. Turns ratio is with both secondary windings connected in parallel.  
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.  
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.  
2. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms.  
3. Peak primary current drawn at minimum input voltage.  
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
