SLC7649S Series

High Current Power Inductors

Coilcraft’s SLC7649S 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
AEC-Q200 Grade 3 (–40°C to +85°C)

Notes

When ordering, please specify termination and packaging codes: e.g. SLC7649S-151KLC
Inductance measured at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
DCR measured at 25°C on a micro-ohmmeter at the points indicated in this 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 a 20% (typ) inductance drop from its value without current. Temperature derating curves.
Irms: Current that causes 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.

Termination:

L = RoHS compliant matte tin over nickel over copper.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (250 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 (1000 per full reel). Factory order only, not stocked.
