Shielded Power Inductors
–
SLC1175
The SLC1175 is designed for high-speed switch mode
applications requiring low inductance and very high
saturation current ratings. While requiring a mere quar-
ter square inch of board space, it can handle saturating
current over 100 A.
This series offers several inductance values not available
in other high current series.
These shielded inductors are ideal for use in multi-phase
VRM/VRD regulators and high current/high frequency
DC/DC converters.

1. When ordering, please specify packaging code:
SLC1175-301MEC
Core material Ferrite
Environment RoHS compliant, halogen free
Terminations RoHS compliant matte tin over nickel over copper.
Other terminations available at additional cost.
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (150 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.
Weight 2.19 – 2.30 g
Ambient temperature –40°C to +85°C with Irms current, +85°C to
+125°C with derated current
D = 13″ machine-ready reel. EIA-481 embossed plastic
Storage temperature Component: –40°C to +125°C.
Tape and reel packaging: –40°C to +80°C
tape. Factory order only, not stocked (700 per full reel).
2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4284.
3. DCR is measured between the two points indicated below.
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332
Packaging 150/7″ reel, 700/13″ reel; Plastic tape: 24 mm wide, 0.4
mm thick, 12 mm pocket spacing, 7.62 mm pocket depth
Points used for measuring DCR
PCB washing Tested with pure water or alcohol only. For other
solvents, see Doc787_PCB_Washing.pdf.
4. SRF measured using an Agilent/HP 8753ES network analyzer or equivalent.
5. DC current at which the inductance drops from its value without current.
6. Current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
