Notes
  1. When ordering, please specify termination and packaging codes: e.g. MSS5131H-474MEC
  2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B LCR meter or equivalent.
  3. SRF measured using an Agilent/HP 4191A or equivalent. Details
  4. Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
    Temperature derating curves.
  5. 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:

  • E = RoHS compliant matte tin over nickel over phos bronze.
  • Q = RoHS tin-silver-copper (95.5/4/0.5) over gold over nickel over phos bronze (Special order, added cost)
  • P = 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). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape. Factory order only, not stocked (2500 parts per full reel).
