SLC1049 Series
High Current Power Inductors

  • Saturation current ratings up to 61 Amps!
  • Exceptionally low DC resistance at 3.3% tolerance
  • Ideal for VRM/VRD regulators
  • Small footprint – requires only 70 sq mm of board space
  • RoHS compliant. 260°C compatible. Matte tin over nickel over copper terminations.
  • COTS Plus tin-silver-copper and tin-lead terminations available
  • Need parts for space, military or other critical applications? See Coilcraft CPS 534PMM series.

1 When ordering, please specify termination and packaging codes: e.g. SLC1049-151MLC
  Termination: L = RoHS compliant matte tin over nickel over copper
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
= non-RoHS tin-lead (63/37).


C = 7" reel, machine-ready 
EIA-481 embossed plastic tape (250 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel
In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
D = 13" reel, machine-ready 

EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel).
2 Inductance measured at 100 kHz, 0.1 Vrms, using an Agilent/HP 4263B LCR meter or equivalent.
3 DCR measured at 25°C on a micro-ohmmeter at the points indicated in this diagram.
4 SRF measured using an Agilent/HP 4191A network analyzer.  Details
5 Isat: DC current at 25°C that causes a 20% (typ) inductance drop from its value without current.
Temperature derating curves.
6 Irms: Current that causes 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
7 Ambient temperature range: −40°C to +85°C with Irms Derating curves
8 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +125°C (Ambient + temperature rise)
10 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.
11 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.
