MSD7342
• Tightcoupling(k≥0.97)and200VisolationmaketheMSD7342
series of coupled inductors ideal for use in a variety of circuits
including flyback, multi-output buck and SEPIC.
• They provide high inductance, high efficiency and excellent
current handling in a rugged, low cost part.
• Can also be used as two single inductors connected in series
or parallel, as a common mode choke or as a 1:1 transformer.

1. When ordering, please specify termination and packaging codes:
MSD7342-105MLC
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: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (250 parts per full reel).
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
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter C instead.
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (1000 parts per
full reel).
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. See temperature rise
calculation.
8. Maximum current when applied to one winding that causes a 40°C
temperature rise from 25°C ambient. See temperature rise calculation.
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.
