MSS6122 Series Shielded
Surface Mount Power Inductors

New RoHS part numbers are shown. Lead was removed from internal connections. Last three characters indicate tolerance, RoHS compliance, and packaging. (View old data sheet.)

  • Magnetically shielded
  • Small footprint, just 6.1 mm square
  • Current rating up to 1.82 Amps
  • Low DC resistance for greater efficiency
  • Inductance ratings from 4.7 to 100 µH
  • RoHS-compliant. 260°C compatible. Gold over nickel over phos bronze terminations
  • COTS Plus tin-silver-copper and tin-lead terminations available
  • For higher current ratings see the MSS6132 Series
  • Samples of all values are available in Coilcraft Designer's Kit C363

1 When ordering, please specify termination and packaging codes: e.g. MSS6122-104MLC
  Termination: L = RoHS compliant gold over nickel over phos bronze
Special order, added cost: 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 RS-481 clear plastic tape (500 parts per full reel).
B = Less than full reel
In tape, not machine ready.  To have a leader and trailer added ($25 charge), use code letter C instead.
D = 13" reel, machine-ready 
EIA RS-481 clear plastic tape. Factory order only, not stocked (1500 parts per full reel).
2 Inductance measured at 100 kHz, 0.1 Vrms.
3 SRF measured using Agilent/HP 8753D network analyzer and Coilcraft SMD-D test fixture. Details
4 Isat: DC current at which the inductance drops 10% (typ) from its value without current. Details
5 Irms: Current that causes the specified temperature rise from 25°C ambient. Details
6 Ambient temperature range: –40°C to +85°C with Irms current.
+85°C to +125°C with derated current Derating curve
7 Storage temperature range: Component: –40°C to +125°C
Packaging: –55°C to +80°C
8 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
9 Electrical specifications at 25°C.
See Qualification Standards for complete environmental and test data.
