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 significantly smaller part.

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.
