Notes
  1. When ordering, please specify termination and packaging codes: e.g. MSS1812T-105KED
  2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD-A fixture in an Agilent/HP 4263B LCR meter or equivalent.
  3. DCR measured at 25°C on a micro-ohmmeter and a Coilcraft CCF858 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
  4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD -D test fixture.
  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:

  • E = RoHS compliant matte tin over nickel over phos bronze.
  • 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:

  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (175 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
Environmental
