注释

When ordering, please specify termination and packaging codes: e.g. MSD1278-105KLC
Frequency at which the differential mode attenuation equals 3 dB
Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent.
Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
DCR is for each winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Interwinding isolation (hipot) tested for one minute.

端子:

L = RoHS compliant matte 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 (500 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.
