1. When ordering, please specify
packaging
code:
LPD5030V-224MEC
Packaging: C
= 7″ machine-ready reel. EIA-481 embossed plastic
tape (750 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 (2500 parts per
full reel).
2. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc on
an Agilent/HP 4284A LCR meter or equivalent.
3. Peak primary current drawn at minimum input voltage.
4. DCR is for each winding.
5. Leakage inductance is for the primary winding with the secondary wind-
ings shorted.
6. Designed to provide Functional Insulation only; does not protect against
electrical shock; nor intended for the isolation of SELV circuits from
Hazardous Voltage circuits.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

1. When ordering, please specify
packaging
code:
LPD5030V-224MEC
Packaging: C
= 7″ machine-ready reel. EIA-481 embossed plastic
tape (750 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 (2500 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. Designed to provide Functional Insulation only; does not protect against
electrical shock; nor intended for the isolation of SELV circuits from
Hazardous Voltage circuits.
7. 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.
8. Equal current when applied to each winding simultaneously that causes a
40°C temperature rise from 25°C ambient. See temperature rise calculation.
9. Maximum current when applied to one winding that causes a 40°C
temperature rise from 25°C ambient. See temperature rise calculation.
10. 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.
