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
producetheLPO1704indefinitely.
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,PCCards,mobilephonesand
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.
