SLR1190 Series

High Current Shielded Power Inductors

Coilcraft’s SLR1190 Series of high-current shielded power inductors feature sub-milliohm DC resistance and very high current handling. Magnetic shielding and tight DCR tolerances make them ideal for low voltage multi-phase VRM/VRD/EVRD regulators and current sensing circuits.

Tight DCR tolerance for inductor-DCR-based current sensing circuits
Three versions for optimal efficiency and accuracy
Ferrite construction for flat L vs I with high current
Magnetic shielding allows high-density packaging
Ideal for multi-phase VRM/VRD/EVRD regulators

Hinweise

When ordering, please specify packaging code: e.g. SLR1190-311KEC
Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4284.
DCR measured at 25°C on a micro-ohmmeter at the points indicated in the diagram. For other operating temperatures, use this DCR at Temperature calculator.
Isat: DC current that causes a 20% (typ) inductance drop from its value without current. Temperature derating curves.
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.
Irms testing was performed on 0.75 inch wide × 0.25 inch thick copper traces in still air. Temperature rise is highly dependent on many factors including pcb land pattern, trace size, and proximity to other components. Therefore temperature rise should be verified in application conditions.

Anschlüsse:

RoHS compliant matte tin over nickel over copper.

Verpackung:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (100 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (450 parts per full reel).
