Shielded Power Inductors – DS1608C
These shielded inductors can help achieve significantly
longer battery life in handheld devices and other portable
products.
They offer high efficiency and small size.Their flat top and
heat resistant materials ensure trouble-free assembly and
reflow operations.

Coilcraft will continue to manufacture and support
the DS1608C indefinitely. For new designs, consider
the MSS7341, MSS1038 or LPS4018 as alternatives.
These series are more cost effective and offer better
current handling. In addition, the LPS4018 is a signifi-
cantly smaller part.
