Hinweise
  1. When ordering, please specify termination code: e.g. MSS1278H-105KED
  2. Inductance measured at 100 kHz, 0.1 Vrms using a Coilcraft SMD-A fixture in an Agilent/HP 4263B LCR meter or equivalent.
  3. DCR measured 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 8573D network analyzer or equivalent. Details
  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.
