SLC7649 Series
High Current Power Inductors

  • Saturation current ratings up to 100 Amps!
  • Exceptionally low DC resistance at 5% tolerance
  • Ideal for VRM/VRD regulators
  • Small footprint – requires less than 60 mm2 board space
  • Tight inductance tolerance – 10% for all values
  • RoHS compliant. 260°C compatible. Matte tin over nickel over copper terminations.
  • COTS Plus tin-silver-copper and tin-lead terminations available

1 When ordering, please specify termination and packaging codes: e.g. SLC7649S-101MLC
  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 on a micro-ohmmeter. Connection points for measuring DCR
4 SRF measured using an Agilent/HP 8753ES network analyzer or equivalent. Details
5 Isat: DC current at which inductance drops 20% (typ) from its value without current. Details
6 Irms: Current that causes a 40°C temperature rise from 25°C ambient. Details
7 Ambient temperature range: –40°C to +85°C with Irms current.
+85°C to +125°C with derated current Derating curve
8 Storage temperature range: Component: –40°C to +125°C
Packaging: –55°C to +80°C
9 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.
10 Electrical specifications at 25°C.
See Qualification Standards for complete environmental and test data.
