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).
  • B = Less than full reel
    On reel 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 (2200 parts per full reel.
