注释

Output is with the secondary windings connected in parallel.
When ordering, please specify packaging code: e.g. FA2677-ALD
Inductance is for the primary, measured at 250 kHz, 0.7 Vrms, 0 Adc.
DCR for the primary and the secondary is with windings connected in parallel.
Leakage inductance measured on the primary windings with all secondary pins shorted.
Turns ratios are with the primary windings and the secondary windings connected in parallel.
1500 Vrms isolation from primary and auxiliary to secondary.

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 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.
