Notes

When ordering, please specify packaging code: e.g. FA2519-ALD
Inductance is for the primary, measured at 250 kHz, 0.7 Vrms, 0 Adc.
Ipk is the peak current drawn at minimum input voltage.
DCR for the primary and for the secondary is with the windings connected in parallel.
Leakage inductance measured on the primary windings with all secondary pins shorted.
Turns ratio is with the primary windings and the secondary windings connected in parallel.
Isolation is from primary and auxiliary windings to secondary windings for one minute.

Termination:

RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations.

Packaging:

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