  1. When ordering, please specify termination and screening codes: e.g. CP312PHA473KLZ.
  2. Inductance measured at 100 kHz, 0.1 Vrms, using a Coilcraft SMD -A fixture in Agilent/HP 4263B LCR meter.
  3. DCR measured on a micro-ohmmeter and a Coilcraft CCF1010 test fixture.
  4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft CCF1232 test fixture.
  5. DC current at which the inductance drops 10% (typ) from its value without current.
  6. Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
