メモ

When ordering, please specify packaging code: e.g. SD43-683KLC
Inductance measured at 100 kHz, 0.1 Vrms using an Agilent/HP 4284A impedance analyzer or equivalent.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using Agilent/HP 8753D network analyzer and Coilcraft SMD-D test fixture. Details
Isat: DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves.
Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.

終端処理:

RoHS compliant tin-silver-copper solder over tin over nickel over silver plating.

パッケージ:

C = 7″ 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 C.
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2000 parts per full reel).
