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

termination and packaging codes:

DS1608C-106MLC

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. DC current at which the inductance drops 30% (typ.) from its value with-

out current.

4. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

Core material Ferrite

Terminations RoHS compliant gold over nickel over moly-manganese.

Other terminations available at additional cost.
