注释

When ordering, please specify a packaging code: FCT1-50M22SLD
Inductance is measured at 250 kHz, 0.1 Vrms, 0 Adc.
1500 Vrms isolation from primary and bias to secondary.
DCR for the secondary is measured with the windings connected in parallel.
Leakage inductance is for the primary and is measured with the secondary shorted.
Turns ratio is with the secondary windings connected in parallel.
Output is with the secondary windings connected in parallel. Bias winding output is 12 V, 20 mA.

端子:

RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations. Other terminations available at additional cost.

包装:

D = 13" machine-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.
