SLC1049 Series
High Current Power Inductors

  • Saturation current ratings up to 61 Amps!
  • Exceptionally low DC resistance at 5% 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
S
= non-RoHS tin-lead (63/37).
Packaging:

 

C = 7" reel, machine-ready 
EIA-481 embossed plastic tape (250 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" 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.
