Notes

Output is with the secondary windings connected in parallel. Auxiliary winding output is 10 V, 20 mA.
When ordering, please specify packaging code: e.g. FCT1-150K2SLD
Inductance is measured at 250 kHz, 0.2 Vrms, 0 Adc.
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.
1500 Vrms primary to secondary isolation.

Termination:

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

Packaging:

D = 13″ machine ready reel. EIA-481 embossed plastic tape (350 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. To simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
