The MSD1260T series of shielded coupled inductors was
designed specifically for high temperature applications –
up to 125°C ambient.
Tight coupling (k ≥ 0.97) and 500 Vrms isolation make them
ideal for use in a variety of circuits including flyback, multi-
output buck, SEPIC and Zeta. These parts provide high
inductance, high efficiency and excellent current handling.
They can also be used as two single inductors connected
in series or parallel or as a common mode choke.

1. When ordering, please specify termination and packaging codes:
MSD1260T-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).
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (500 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. Leakage inductance is for L1 and is measured with L2 shorted.
6. 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.
7. Equal current when applied to each winding simultaneously that
causes a 40°C temperature rise from 25°C ambient.
8. Maximum current when applied to one winding that causes a 40°C
temperature rise from 25°C ambient.
9. 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.
