Notes
  1. When ordering, please specify packaging code: e.g. 1812WBT1.5-4LC
  2. Inductance is per winding.
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.

Termination:

  • L = RoHS compliant gold over nickel over moly-manganese.
  • T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). (Special order)

Packaging:

  • C = 7″ machine-ready reel. EIA-481 embossed plastic tape (600 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. Factory order only, not stocked (2200 parts per full reel).
