LPD5030 and other Applications
The LPD5030 coupled miniature shielded inductors are
only 3 mm high and 5 mm square. They are ideal for
use in a variety of circuits including flyback, multi-output
buck and SEPIC.
These inductors provide high inductance, high efficiency
and excellent current handling in a rugged, low cost part.
They can also be used as two single inductors connected
in series or parallel or as a common mode choke.

1. Please specify termination and packaging codes:
LPD5030-105MEC
Termination:E = RoHS compliant, halogen free silver-palladium-
platinum-glass frit.
Temperature rise calculation based on specified Irms
Winding power loss = (I 2 + I 2) × DCR in Watts (W)
L1
L2
90°C
W
Temperature rise = Winding power loss ×
Special order:
T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Examples for LPD5030-472ME:
Equal current in each winding (1.4 A):
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
Winding power loss = (1.42 +1.42) × 0.111 = 0.435 W
tape (750 parts per full reel).
90°C
W
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.
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (2500 parts per
full reel).
Temperature rise = 0.435 W ×
= 39.2°C
Unequal current (IL1 = 1.8 A, IL2 = 0.8 A):
Winding power loss = (1.82 +0.82) × 0.111 = 0.431 W
90°C
W
Temperature rise = 0.431 W ×
= 38.8°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.
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. Visit www.coilcraft.com/coupledloss.
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.
