1. Please specify termination and packaging codes:
MSS5121-394M
LC
Termination: L = RoHS compliant gold over nickel over
phos bronze
Special order:
T = RoHS tin-silver-copper (95.5/4/0.5)
or S = non-RoHS tin-lead (63/37).
Packaging: C=7
″ machine-ready reel. EIA-481
embossed plastic tape (600 parts per
full reel).
B= Less than full reel. In tape, but not
machine ready.
To have a leader and trailer added
($25 charge), use code letter C
instead.
D=13
″ machine-ready reel. EIA-481
embossed plastic tape. Factory order
only, not stocked (2500 parts per full
reel).
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc
using Coilcraft SMD-A fixture in an Agilent/HP 4284A
impedance analyzer.
3. SRF measured using an Agilent/HP 8753D network
analyzer and a Coilcraft SMD-D test fixture.
4. DC current at which the inductance drops the specified
amount from its value without current.
5. Current that causes the specified temperature rise for
25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components”
before soldering.
• Low profile shielded power inductors
• Low DCR, excellent current handling and low cost
