MSD1583T Series

Shielded Coupled Power Inductors

Coilcraft's MSD1583T Series of 1:1 high-temperature coupled power inductors are used in Flyback, SEPIC, Ćuk, Zeta and other applications. The MSD_T family features magnetic shielding for compact packaging and tight winding-to-winding coupling.

Excellent coupling coefficient (k ≥ 0.98)
Ideal for use in a variety of circuits including flyback, multi-output buck, SEPIC, Zeta, and Ćuk.
High inductance, high efficiency and excellent current handling.
In SEPIC topologies, the required inductance for each winding is half the value needed for two separate inductors, allowing selection of a part with lower DCR and higher current handling.
AEC-Q200 qualified

Notes

When ordering, please specify termination code: e.g. MSD1583T-105KED
Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent.
For SEPIC: When leads are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value.
DCR is for each winding. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
For SEPIC: When leads are connected in parallel, DCR is half the value. When leads are connected in series, DCR is twice the value.
SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value.
Leakage inductance is for the primary winding (L1) with the secondary winding (L2) shorted.
Isat: DC current that causes the primary inductance drop of 30% (typ) from its value without current.
Irms, both windings: Equal current when applied to each winding simultaneously that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Determine temperature rise.
Irms, one winding: Current when applied to one winding that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Determine temperature rise.

Termination:

E = Halogen free component. RoHS compliant matte tin over nickel over phos bronze terminations.
Q = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
P = non-RoHS tin-lead (63/37). (Special order, added cost)
