1. When ordering, please specify packaging code:
LPD5030V-224MRC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (750 parts per full reel). Quantities less than full
reel available: in tape (not machine ready) or withleader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating the needfor multiple packaging codes. When ordering, simply
change the last letter of your part number from B to C.
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (2500 parts perfull reel).

2. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc onan 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 windings shorted.
6. 1000 Vrms, one minute isolation (hipot) between windings. Designed
to provide Functional Insulation only; does not protect against electricalshock; 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.

D = 13″ machine-ready reel. EIA-481 embossed plastictape. Factory order only, not stocked (2500 parts perfull 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 areconnected 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 halfthe value. When leads are connected in series, DCR is twice the value.
4. SRF measured using an Agilent/HP 4191A or equivalent. When leads areconnected in parallel, SRF is the same value.
5. Leakage Inductance is for L1 and is measured with L2 shorted.

6. 1000 Vrms, one minute isolation (hipot) between windings. Designed
to provide Functional Insulation only; does not protect against electricalshock; nor intended for the isolation of SELV circuits from Hazardous Voltage circuits.
7. DC current at 25°C that causes the specified inductance drop 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 a40°C temperature rise from 25°C ambient. This information is for referenceonly and does not represent absolute maximum ratings.
9. Maximum current when applied to one winding that causes a 40°C temperature rise from 25°C ambient. This information is for reference only anddoes not represent absolute maximum ratings.
10. Electrical specifications at 25°C.
Refer to Doc 639 “Selecting Coupled Inductors for SEPIC Applications.”
