SLC1480 Series

High Current Shielded Power Inductors

Coilcraft’s SLC1480 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.

Sub-milliohm DC resistance and tight DCR tolerance
Ferrite construction for flat L vs I with high current
Magnetic shielding allows high-density packaging
Designed for high-speed switch mode applications.
Ideal for multi-phase VRM/VRD/EVRD regulators

Notes

When ordering, please specify packaging code: e.g. SLC1480-441MLD
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.
SRF measured using an Agilent/HP 8753ES network analyzer or equivalent.
Isat: DC current at 25°C that causes the specified 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.

Termination:

RoHS compliant matte tin over nickel over copper. Other terminations available at additional cost.

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape (500 per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = 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 D.
