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.

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.

1. When ordering, please specify
tolerance, termination
and
packaging
codes:
DS1608C-106MLC
Tolerance: M
= 20%,
K
= 10%,
J
= 5% (Table above shows stock tolerances in bold.)
Termination: L
= RoHS compliant gold over nickel over moly-manganese
Special order: T
= RoHS tin-silver-copper (95.5/4/0.5) or
S
= non-RoHS tin-lead (63/37).
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.
D
= 13″ machine-ready reel. EIA-481 embossed plastic tape (2500 parts per full reel).
2. Inductance tested at 0.1 Vrms, 100 kHz, 0 Adc.
3. Tolerances in bold are stocked for immediate shipment.
4. DC current at which the inductance drops 30% (typ.) from its value without current.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
