Notes
  1. When ordering, please specify termination and packaging codes: e.g. MSS1278-105KLD
  2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using 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 4191A or equivalent.
  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.
  • T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
  • S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape (500 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • B = Less than full reel. 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 D.
