Notes:
1. Test frequency is specified as the frequency for measuring the inductance.
2. Rated D.C. current indicates the value of the current when the inductance is 25% lower than its initial value
and the temperature rising
∆
T=40 C at D.C. Superposition.
o
3. Operating temperature range: -30ºC to +80ºC.
4. 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.
5. Contact EEMPL for RoHS compliant version availability.
