1. When ordering, please specify a packaging code:

2. Inductance is measured at 250 kHz, 0.2 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.

7. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

Secondary winding 7 – 6 not used on FCT1-120K2SL

and FCT1-150K2SL. For other parts, secondary
