MSD1260
The excellent coupling coefficient (k ≥ 0.94) makes the
MSD1260 series of coupled inductors ideal for use in
SEPIC applications. In SEPIC topologies, the required
inductance for each winding in a coupled inductor is half
the value needed for two separate inductors, allowing
selection of a part with lower DCR and higher current
handling.
These parts provide high inductance, high efficiency
and excellent current handling in a rugged, low cost
part. They are also well suited for use as a VRM
inductors in high-current DC-DC converters and VRM/
VRD controllers.
They can also be used as two single inductors con-
nected in series or parallel, as a common mode choke
or as a 1 : 1 transformer.

1. When ordering, please specify termination and packaging codes:
MSD1260-105KLD
Termination: L = RoHS compliant matte tin over nickel over phos bronze.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).

Winding power loss = (IL12 + IL22) × DCR

Temperature rise (Δt) = Winding power loss ×
55.6°C
Δt = (IL12 + IL22) × DCR ×
W
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (500 parts per full reel).
Example 1. MSD1260-153ML (Equal current in each winding)
Winding power loss = (2.062 +2.062) × 0.085 = 0.721 W
55.6°C
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.
Δt = 0.721 W ×
= 40°C
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.
W
Example 2. MSD1260-153ML (IL1 = 2.4 A, IL2 = 1.3 A)
Winding power loss = (2.42 +1.32) × 0.085 = 0.633 W
55.6°C
Δt = 0.633 W ×
= 35.2°C
W
4. SRF measured using an Agilent/HP 4191A or equivalent. When leads
are connected in parallel, SRF is the same value.
Coupled Inductor Core and Winding Loss Calculator
5. DC current, at which the inductance drops 30% (typ) 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. See temperature rise
calculation.
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. Visit www.coilcraft.com/coupledloss.
7. Maximum current when applied to one winding that causes a 40°C
temperature rise from 25°C ambient. See temperature rise calculation.
8. Electrical specifications at 25°C.
