Shielded Power Inductors – SLC1175
• Ideal for use in multi-phase VRM/VRD regulators and high current/high frequency DC/DC converters.
• Offers inductance values unavailable in other high current series.

1. When ordering, please specify packaging code:
SLC1175-301MEC 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. D = 13″ machine-ready reel. EIA-481 embossed plastic 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.
4. SRF measured using an Agilent/HP 8753ES network analyzer or equivalent. 5. DC current at 25°C that causes the specified inductance drop from its
value without current. Click for temperature derating information. 6. Current that causes the specified temperature rise from 25°C ambient.
This information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
