SMTPowerInductors-LPO1704Series
Document 233-1
Document 233-1
Revised 01/27/05
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.

1. When ordering, please specify packaging code:
LPO1704-334ML
C
Packaging: C =7
″ machine-ready reel. EIA-481 embossed plastic
tape (1000 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.
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.
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.
