Note:
- All test data is reference to 25 ambient.
- Test Condition: 100kHz, 0.1Vrms
- Saturation current (Isat): the actual value of DC current when the inductance decreases 30% of its initial value.
- Temperature rise current (Irms): the actual value of DC current when the temperature rise is T40 (Ta=25).
- Circuit design, component placement, PCB size and thickness, cooling system, and etc., all will affect the product temperature. Please verify the product temperature in the final application.
