1. Please specify termination and packaging codes:
LPD3015-334M
LC
Termination: L = RoHS compliant Silver-palladium-platinum-glass frit.
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 (1000 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.
D =13
″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (3500 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. 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.
Temperature rise calculation based on specified Irms
Temperature rise = Winding power loss ×
135°C
W
Winding power loss = (
+
) × DCR in Watts (W)

Equal current in each winding (1.2 A):
Winding power loss = (1.2 + 1.2 ) × 0.204 = 0.301 W
Temperature rise = 0.301 W ×
135°C
W
= 40.6°C

Unequal current (
= 1.0 A,
= 0.6 A)

:
Winding power loss = (1.0 + 0.6 ) × 0.204 = 0.277 W
Temperature rise = 0.277 W ×

= 37.4°C
