Notes
  1. When ordering, please specify termination and packaging codes: e.g. LPR4012-223DMRC
  2. Inductance is measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent.
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator
  4. SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value.
  5. Isat: DC current applied to L1 at which the inductance drops the specified amount from its value without current.
  6. Irms: Current applied to L1 that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Determine temperature rise.

Termination:

  • R = Matte tin over nickel over silver.
  • Q = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
  • P = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape 1000 parts per full reel).
  • B = 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 (3500 parts per full reel).
