Notes

When ordering, please specify termination and packaging codes: e.g. MSS7341T-474MLD
Inductance measured at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD -D test fixture.
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.

Termination:

L = RoHS compliant matte tin over nickel over phos bronze.
T = RoHS tin-silver-copper (95.5/4/0.5) over gold over nickel over phos bronze. (Special order, added cost)
S = non-RoHS tin-lead (63/37) over gold over nickel over phos bronze. (Special order, added cost)

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (300 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastic tape (1200 parts per full reel).
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.
