Shielded Power Inductors – SLC1175 Document 838-1 Document 838-1 Revised 02/22/11 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 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. Points used for measuring DCR 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.
