Test Conditions
- All test data is referenced to 25 ambient.
- Inductance measure condition at 100kHz, 1.0V.
- Rated current: Isat or Irms, whichever is smaller.
- Saturation current (Isat): the actual value of DC current when the inductance decreases approximately 30% of its initial value.
- Temperature rise current (Irms): the actual value of DC current when the temperature rise is T40 (Ta=25).
- Electrode Coplanarity: 0.1mm Max.
