1. When ordering, please specify a packaging code:
FCT1-50K2SLD
Packaging: D = 13machine ready reel. EIA-481 embossed plastic tape
(350 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.
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.
