Notes
  1. When ordering, please specify packaging code: e.g. 1812DPS-473MLC
  2. Inductance is per winding. Tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
  3. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. Isat: DC current at 25°C that causes a 10% inductance drop from its value without current. Temperature derating curves.
  5. Irms: Current that causes 40°C (typ) temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Termination:

  • RoHS compliant gold over nickel over moly-manganese.

Packaging:

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