The PFD3215 has a footprint less than 3.2 × 2.3 mm,
making this shielded coupled inductor ideal for applications
with limited board space. It is designed for use in a variety
of circuits including flyback, multi-output buck and SEPIC.
These inductors provide high efficiency and excellent cur-
rent handling in a rugged, low cost part.
They can also be used as two single inductors connected
in series or parallel, as a wideband transformers or as a
common mode choke.

1. When ordering, please specify packaging code:
PFD3215-103MEC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic tape
(2000 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 C
instead.
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Fac-
tory order only, not stocked (7500 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 the primary winding with the secondary windings
shorted.
6. DC current, at which the inductance drops the specified amount from its value
without current. It is the current flowing in one winding.
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.

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.

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. Leakage inductance is for the primary winding with the secondary
windings shorted.
5. Electrical specifications at 25°C.
