SLC1175 Series High Current
Shielded Power Inductors

  • Designed for high-speed switch mode applications.
  • Handles current over 100 Amps!
  • Magnetic shielding allows high-density mounting.
  • Ideal for use in multiphase VRM/VRD regulators and high current / high frequency DC/DC converters.
  • RoHS-compliant, halogen free. 260°C compatible. Matte tin over nickel over copper terminations
  • Select values of SLC and SLR are available in Coilcraft Designer's Kit C467

1 When ordering, please specify packaging code: e.g. SLC1175-301MEC
Packaging:

 

C = 7" reel, machine-ready 
EIA-481 embossed plastic tape (150 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" machine-ready reel
EIA-481 embossed plastic tape. Factory order only, not stocked (700 parts per full reel).
2 Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4284.
3 DCR measured at 25°C on a micro-ohmmeter at the points indicated in this diagram. For other operating temperatures, use this DCR at Temperature calculator.
4 SRF measured using an Agilent/HP 8753ES network analyzer or equivalent.
5 Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
Temperature derating curves.
6 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.
7 Ambient temperature range: −40°C to +85°C with (40°C rise) 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.
