Notes
  1. When ordering, please specify termination and packaging codes: e.g. MSS5131-394MLC
  2. Inductance measured 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. SRF measured using Agilent/HP 4191A or equilvalent.
  5. Isat: DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves.
  6. Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves

Termination:

  • L = RoHS compliant matte tin over nickel over phos bronze (current production) or gold over nickel over phos bronze (prior production).
  • T = RoHS tin-silver-copper (95.5/4/0.5) over gold over nickel over phos bronze. (Special order, added cost)
  • S = non-RoHS tin-lead (63/37) over gold over nickel over phos bronze. (Special order, added cost)

Packaging:

  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape (600 parts per full reel).
  • B = Less than full reel 
    In tape, 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 (2500 parts per full reel)
