DS1608C Series

Shielded Surface Mount Power Inductors

We will continue to manufacture and support the DS1608C indefinitely, however for new designs, we recommend the LPS4018, MSS7341 or MSS1038 as alternatives. These series are more cost effective and offer better current handling.

Notes

When ordering, please specify termination and packaging codes: e.g. DS1608C-106MLC
Inductance tested at 0.1 Vrms, 100 kHz
Tolerances in bold are stocked for immediate shipment.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Isat: DC current at which the inductance drops 30% (typ.) from its value without current. Details

Tolerance:

M = 20%, K = 10%, J = 5% (Table above shows stock tolerances in bold.)

Termination:

L = Gold over nickel over moly-manganese.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (750 parts per full reel).
D = 13″ machine-ready reel. EIA-481 embossed plastic tape (2500 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
