bronze (current production) or gold over nickel over phos bronze (prior
production). Other terminations available at additional cost.
Weight 141 – 147 mg
Ambient temperature –40°C to +85°C with Irms current, +85°C to
+125°C with derated current
Storage temperature Component: –40°C to +125°C.
Tape and reel packaging: –40°C to +80°C
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332
Packaging 600/7″ reel, 2500/13″ reel; Plastic tape: 12 mm wide,
0.35 mm thick, 8 mm pocket spacing, 3.25 mm pocket depth
PCB washing Tested with pure water or alcohol only. For other solvents,
see Doc787_PCB_Washing.pdf.
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 = 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
