注释

When ordering, please specify termination code: e.g. MSS1278H-105KED
Inductance measured at 100 kHz, 0.1 Vrms using a Coilcraft SMD-A fixture in an Agilent/HP 4263B LCR meter or equivalent.
DCR measured on a micro-ohmmeter and a Coilcraft CCF858 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using an Agilent/HP 8573D network analyzer or equivalent. 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.

端子:

E = 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).
