SLC1049 Series

High Current Power Inductors

Coilcraft’s SLC1049 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
Ideal for multi-phase VRM/VRD/EVRD regulators

Hinweise

When ordering, please specify termination and packaging codes: e.g. SLC1049-151MLC
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.
SRF measured with coils connected in series 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.

Anschlüsse:

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)

Verpackung:

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 = 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.
