1260 COUPLED INDUCTORS
High Reliability Coupled Inductors
MS590PND
The MS590PND series of shielded coupled inductors was
designed specifically for high temperature applications –
up to 155°C. Tin-lead (Sn-Pb) terminations are used for
the best possible board adhesion.
The excellent coupling coefficient (k
≥
0.98) makes it ideal
for use in SEPIC applications. In SEPIC topologies, the
required inductance for each winding in a coupled induc-
tor is half the value needed for two separate inductors,
allowing selection of a part with lower DCR and higher
current handling.
These inductors provide high inductance, high efficiency,
excellent current handling and 500 V isolation in a very
rugged part. They are well suited for use as VRM induc-
tors in high-current DC-DC and VRM/VRD controllers.
They can also be used as two single inductors connected
in series or parallel, as a common mode choke or as a
1 : 1 transformer.

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. See temperature
rise calculation.
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.
Refer to Doc 639 “Selecting Coupled Inductors for SEPIC Applications.”
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
