Notes:
1. Add the tolerance code of inductance by replacing “X” of the part number by: M=
±20%
or N=
±30%
2. Inductance is tested at 100kHz.
3. Saturation current, Isat, indicates the value of DC current when the inductance is 35% typical (while the
tolerance is
±30%
) or 25% typical (while the tolerance is
±20%
) 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.
