Notes:
1. Inductance is tested at 0.1Vrms, 100kHz.
2. The rated current is either 85% of the saturation current or the heating current depending on which value is
lower. In this case, the rated current is 10.7A.
3. Saturation current, Isat, indicates the value of DC current when the inductance is 30% typical lower than its
initial value.
4. Heating current, Irms, is the value of current when the temperature rising
∆
T=40 C typical.
o
5. Operating temperature range: -40ºC to +100ºC.
6. The part temperature (ambient temperature + temperature rise) should not exceed the upper limit of the
operating temperature under worst case operating conditions. Circuit design, component placement, PWB
trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part
temperature should be verified in the end application.
7. Contact EEMPL for RoHS compliant version availability.
