注释

When ordering, please specify termination and packaging codes: e.g. FA2469-ALD
Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance measured between pins 1 and 3 with pins 4 and 6 shorted.
1500 Vdc interwinding isolation.

端子:

L = RoHS compliant 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 (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. 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.
