| Document 186-1 SMT Power Inductors - DS1608C Series 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.

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 without current. 4. Ambient temperature range: -40C to +85C 5. Storage temperature range: Component: -40C to +85C Packaging: -55C to +80C 6. Resistance to soldering heat: Three reflows at >217C for 90 seconds (+260C 5C for 20 - 40 seconds), allowing parts to cool to room temperature between. 7. Electrical specifications at 25C. See Qualification Standards section for environmental and test data. Refer to Doc 362 "Soldering Surface Mount Components" before soldering. Specifications subject to change without notice.
