Coupled Inductors MSD1514
• Excellent coupling coefficient (k ≥ 0.97)
• 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.

1. When ordering, please specify termination and packaging codes:
MSD1514-105KED
Termination: E = RoHS compliant matte tin over nickel over phos bronze.
Special order: Q = RoHS tin-silver-copper (95.5/4/0.5)
or P = non-RoHS tin-lead (63/37).
Coupled Inductor Core and Winding Loss Calculator
This web-based utility allows you to enter frequency, peak-to-peak
(ripple) current, and Irms current to predict temperature rise and overall
losses, including core loss. Go to online calculator.
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (175 parts per full reel).
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge),
use code letter D instead.
2. 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.
3. 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.
4. SRF measured using an Agilent/HP 4191A or equivalent.When leads
are connected in parallel, SRF is the same value.
5. DC current at which the inductance drops the specified amount from its
value without current. It is the sum of the current flowing in both windings.
6. Equal current when applied to each winding simultaneously that
causes a 40°C temperature rise from 25°C ambient.
Click for temperature derating information.
7. 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.
Click for temperature derating information.
8. Electrical specifications at 25°C.
Refer to Doc 639 “Selecting Coupled Inductors for SEPIC Applications.”
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
