N/A

  • Inductance measured at 100 kHz, 1.0 Vrms, 0 Adc on Agilent/HP 4284A LCR meter or Equivalent.
  • DCR measured on GW Instek GOM-802 Microhmmeter or Equivalent.
  • DC Current at 25°C resulting in % drop of inductance from zero current. Isat is the more critical current specification when less than Irms.
  • Current that causes a specificed temperature rise in an inductor from 25°C ambient. This specification is for reference only as the actual Temperature Rise will depends on the type of wires used and the cooling available (convection via airflow, or conduction through mounting to heat sink). The actual Temperature Rise will be much lower as the flat wire has greater surface for heat dissipation under power.
  • SRF measured using Agilent/HP 4395A network analyzer and an Agilent/HP 43961A test fixture.
