SMT Power Inductors - LPO1704 Series
We now offer an improved version of
this series: LPO6610.
It has identical electrical specifications and footprint,
and comes in a more robust package that features part
identification marking. We will, however, continue to
produce the LPO1704 indefinitely.
Measuring just 1 mm high, the
LPO1704 is the world’s lowest pro-
file power inductor!
This series has been specially de-
signed for applications requiring the
smallest possible footprint and low-
est height: notebook computers,
PDAs, PC Cards, mobile phones and
other handheld products.
The specially designed ceramic case totally protects the
winding while the flat top provides the best possible
surface for pick and place handling.

Parts/reel: 7″ 1000 Tape width: 12 mm
For packaging data see Tape and Reel Specifications section.
1. When ordering, please specify packaging code:
LPO1704-334M_
C
=
7” machine-ready reel
EIA-481 embossed plastic tape (1000 per 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.
2. Tested at 100 kHz, 0.1 Vrms, 0 Adc.
3. DC current at which the inductance drops 10% (typ) from its value without
current.
4. Average current for a 40°C rise above 25°C ambient.
5. Operating temperature range -40°C to +85°C.
6. Electrical specifications at 25°C.
See Qualification Standards section for environmental and test data.
