DS1608C Series

Shielded Surface Mount Power Inductors

RoHS compliant
We will continue to manufacture and support the DS1608C indefinitely, however for new designs, we recommend the LPS4018MSS7341 or MSS1038 as alternatives.These series are more cost effective and offer better current handling.

Notes
  1. When ordering, please specify termination and packaging codes: e.g. DS1608C-106MLC
  2. Inductance tested at 0.1 Vrms, 100 kHz
  3. Tolerances in bold are stocked for immediate shipment.
  4. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  5. 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 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" reel, machine-ready 
    EIA-481 embossed plastic tape. Factory order only, not stocked (2500 per full reel).
