Notes

When ordering, please specify termination and packaging codes: e.g. MSS7348T-105MEC
Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD-A fixture in an Agilent/HP 4263B LCR meter.
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. 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.

Termination:

E = RoHS compliant matte tin over nickel over phos bronze (current production) or gold over nickel over phos bronze (prior production).
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 (250 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 (1000 parts per full reel). Factory order only, not stocked.
