15 W Forward Mode Transformers  
• Designed for forward topology operating at 250 kHz  
• Five different outputs from 3.3 V to 15 V; 36 – 75 V input  
• 1500 Vrms isolation from primary and aux to the secondary  
• FCT1-50M2SL was developed for use with National  
Semiconductor LM5015 and is referenced on application note  
AN-1724 as CA2983-CL and on AN-1725 as GA2983-CL.  
Core material Ferrite  
Terminations RoHS tin-silver over tin over nickel over phos  
bronze. Other terminations available at additional cost.  
Weight 6.9 – 7.1 g  
Ambient temperature –40°C to +85°C  
Storage temperature Component: –40°C to +85°C.  
Packaging: –40°C to +80°C  
Resistance to soldering heat Max three 40 second reflows at  
+260°C, parts cooled to room temperature between cycles  
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /  
85% relative humidity)  
Failures in Time (FIT) / Mean Time Between Failures (MTBF)  
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332  
Packaging 175 per 13reel Plastic tape: 32 mm wide, 0.5 mm thick,  
28 mm pocket spacing, 12.93 mm pocket depth

1. When ordering, please specify a packaging code:  
FCT1-50M2SLD  
Packaging: D = 13machine ready reel. EIA-481 embossed plastic tape  
(175 parts per full reel).  
Dot above pin1  
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 measured at 250 kHz, 0.5 Vrms, 0 Adc.  
3. DCR for the secondary is measured with the windings connected in parallel.  
4. Leakage inductance is for the primary and is measured with the secondary shorted.  
5. Turns ratio is with the secondary windings connected in parallel.  
6. Output is with the secondary windings connected in parallel. Auxiliary winding output is  
10 V, 20 mA.
