注释

When ordering, please specify termination and packaging codes: e.g. MSD1583-105KEC
Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. When leads are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value
DCR is for each winding. When leads are connected in parallel, DCR is half the value. When leads are connected in series, DCR is twice the value.
SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value.
Leakage Inductance is for L1 and is measured with L2 shorted.
Isat: DC current, at which the inductance drops the specified amount from its value without current. It is the sum of the current flowing in both windings.
Irms, both windings: Equal current when applied to each winding simultaneously that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Determine temperature rise.
Irms, one winding: Current when applied to one winding that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Determine temperature rise.

端子:

E = Matte tin over nickel over phos bronze.
Q = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
P = 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.
