Miniature Transformers LPD5030V
With 1500 Vdc (1000 Vrms) isolation and a small pack-
age size, the LPD5030V series is ideal for use in high
density isolated circuit applications.
Functional Safety Listed by UL.Functional
insulation class for TNV-1 to SELV applica-
tions. Functional insulation with a maximum
60 Vdc, 42.4 V peak input/output voltages with working
voltages up to 210 Vdc. (Report #E219588-A6)
These miniature transformers provide tight coupling, high
inductance and excellent current handling.
They can be used as
• Flyback transformers
• Coupled inductors in SEPIC applications
• Common mode filter chokes.

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).
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.
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).
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

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. Go to online calculator.
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 25°C that causes the specified inductance drop from its
value without current. It is the sum of the current flowing in both wind-
ings.
8. Equal current when applied to each winding simultaneously that causes
a 40°C temperature rise from 25°C ambient.This information is for
reference only 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 and does not represent absolute maximum ratings.
10. Electrical specifications at 25°C.
