1. When ordering, please specify packaging code:  
2. Inductance is for the primary, measured at 250 kHz, 0.2 Vrms, 0 Adc.  
3. Ipk is peak primary current drawn at minimum input voltage.  
4. DCR for the secondary is per winding.  
5. Leakage inductance measured between pins 3 and 4 with all other pins  
shorted.  
C1586-ALD  
Packaging: D = 13machine-ready reel. EIA-481 embossed plastic  
tape (175 parts 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.  
6. Turns ratio is with the secondary windings connected in parallel.  
7. Output of the secondary is with the windings connected in parallel. Bias  
winding output is 12 V, 20 mA.  
8. Electrical specifications at 25°C.  
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
