1. Please specify termination and packaging codes:
MSS5121-394MLC
Termination:L = RoHS compliant matte tin over nickel
over phos bronze or 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= 7â³ 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= 13â³ 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 SMDÂâA fixture in an Agilent/HP 4284A
impedance analyzer.
3. SRF measured using an Agilent/HP 8753D network
analyzer and a Coilcraft SMDÂâD test fixture.
4. DC current at 25°C that causes the specified induc-
tance drop from its value without current.
Click for temperature derating information.
5. Current that causes the specified temperature rise from
25°C ambient. This information is for reference only and
does not represent absolute maximum ratings.
Click for temperature derating information.
6. Electrical specifications at 25°C.
Refer to Doc 362 âSoldering Surface Mount Componentsâ
before soldering.
