注释

When ordering, please specify packaging code: e.g. FCT1-240D3SLD
Inductance is measured at 250 kHz, 0.2 Vrms, 0 Adc.
DCR for the primary and secondary is with the windings connected in parallel.
Leakage inductance is for the primary windings with the secondary windings shorted.
Turns ratio is with the primary windings and the secondary windings connected in parallel.
1500 Vrms winding to winding isolation.

端子:

L = RoHS tin-silver over tin over nickel over phos bronze.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (63/37). (Special order, added cost)

包装:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape (175 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. In an effort 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.

原理图

The primary windings and the secondary windings are to be
connected in parallel on the PC board.

Transformer	Recommended output inductor
FCT1-33D3SL	SER2013-472
FCT1-50D3SL	SER1360-103
FCT1-120D3SL	MSS1278-563
FCT1-195D3SL	MSS1278-154
FCT1-240D3SL	MSS1278-224

These inductors are recommended for 30% ripple current. Ripple less than 30% may require the use of physically larger inductors. Allowing higher ripple current to make use of smaller inductors may create a risk of discontinuous output current.
