High Reliability Coupled Inductors MS612PND
The MS612PND series of coupled inductors was de-
signed 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 ≥ 0.94) makes it
ideal for use in SEPIC applications. In SEPIC topolo-
gies, the required inductance for each winding in a
coupled inductor is half the value needed for two sepa-
rate inductors, allowing selection of a part with lower
DCR and higher current handling.
These inductors provide high inductance, high effi-
ciency and excellent current handling in a very rugged
part. They are well suited for use as VRM inductors in
high-current DC-DC 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.

Temperature rise calculation based on specified Irms
1. When ordering, please specify testing code:
MS612PND105KSZ

Winding power loss = (IL1

IL22) × DCR in Watts (W)
Testing: Z = COTS
52.6°C

Temperature rise ( t) = Winding power loss ×

N = Screening per Coilcraft CP-SA-10004
52.6°C

2
t = (IL1
+
IL22) × DCR ×
C = Custom screening (please specify when ordering)
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.
Example 1. 612PND153 (Equal current in each winding)
Winding power loss = (2.32 +2.32) × 0.072 = 0.761 W
52.6°C
t = 0.761 W ×
= 40°C
W
Example 2. 612PND153 (
I
L1 = 2.4 A, IL2 = 1.3 A)
Winding power loss = (2.42 +1.32) × 0.072 = 0.536 W
4. SRF measured using an Agilent/HP 4191A or equivalent. When leads
are connected in parallel, SRF is the same value.
5. Typical 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.
52.6°C
W
t = 0.536 W ×
= 28.2°C
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.
