MSD1038V Series

Miniature High-Isolation Coupled Inductors

Coilcraft MSD1038V Series surface-mount 1:1 coupled power inductors feature higher isolation and are suitable for No-opto Isolated Flyback, Isolated Buck/Fly-BuckTM, SEPIC, Cuk, Zeta and other applications. Their compact, low-profile design and magnetic shielding make them ideal for a cost-effective alternative to custom core and bobbin transformers.

High isolation voltage, 2250 Vrms, one minute isolation (hipot) between primary and secondary windings
Ideal for use in a variety of circuits including flyback, multi-output buck, SEPIC, Ćuk and Zeta.
High efficiency and excellent current handling
Provides Functional Insulation
AEC-Q200 qualified

注释

When ordering, please specify termination and packaging codes: e.g. MSD1038V-154KEC
Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. 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. 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 L1 and is measured with L2 shorted.
DC current at 25°C that causes a 30% (typ) inductance drop from its value without current. It is the sum of the current flowing in 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. To predict temperature rise go to online calculator.
Maximum 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. To predict temperature rise go to online calculator.
