MSS7341 Series Shielded
Surface Mount Power Inductors

  • Magnetically shielded
  • Saturation current rating up to 3.72 Amps
  • Low DC resistance for greater efficiency
  • For high-temperature, AEC-Q200 Grade 1 qualified parts, consider the MSS7341T.
  • For a lower profile part with the same footprint, see MSS7331
  • AEC-Q200 Grade 3 (−40°C to +85°C)
  • RoHS-compliant. 260°C compatible. RoHS compliant matte tin over nickel over phos bronze terminations (current production) or gold over nickel over phos bronze terminations (prior production)
  • COTS Plus tin-silver-copper and tin-lead terminations available
  • Samples of all values are available in Coilcraft Designer's Kit C385

1 When ordering, please specify termination and packaging codes: e.g. MSS7341-104MLD
  Termination: L = RoHS compliant matte tin over nickel over phos bronze (current production) or gold over nickel over phos bronze (prior production)
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) over gold over nickel over phos bronze or S = non-RoHS tin-lead (63/37) over gold over nickel over phos bronze.
Packaging: D = 13" reel, machine-ready 
EIA-481 embossed plastic tape (1200 parts per full reel).
C = 7" reel, machine-ready 
EIA-481 embossed plastic tape. Special order (300 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 D instead.
2 Inductance measured at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
3 Tolerances in bold are stocked for immediate shipment.
4 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 SRF measured using an Agilent/HP 8573D network analyzer and a Coilcraft SMD-D test fixture. Details
6 Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
Temperature derating curves.
7 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.
8 Ambient temperature range: −40°C to +85°C with (40°C rise) Irms Derating curves
9 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
10 Maximum part temperature: +125°C (Ambient + temperature rise)
11 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.
12 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
