SMT Power Inductors - LPO4812 Series
The LPO4812 series is designed for
applications requiring the smallest
possible size in a low profile part.
Recommended applications include
notebook computers, PC cards, cel-
lular phone handsets, and handheld
products.
The specially designed cover pro-
vides the best possible surface for pick and place
handling, as well as minimizing the pc board space
required.

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),
