SMT Power Inductors - DS1608C Series
These shielded inductors can help achieve significantly
longer battery life in handheld devices and other portable
products.
Theyofferhighefficiencyandsmallsize.Theirflattopand
heat resistant materials ensure trouble-free assembly
and reflow operations.
For new designs, consider the MSS7341, MSS1038 or
LPS4018 as alternatives to this series. These series are
more cost effective and offer better current handling. In
addition, the LPS4018 is a significantly smaller part. We
will continue to manufacture and support the DS1608C
indefinitely.

Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (750 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.
