DS1608B Series

Backlight Inductors

RoHS compliant
We will continue to manufacture and support the DS1608B 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. DS1608B-105MLC
  2. Inductance tested at 100 kHz, 0.1 Vrms.
  3. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. Irms: Current that causes a 30°C temperature rise from 25°C ambient.This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.

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). 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.
  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape (2500 parts per full reel).
