Notes:
1. Test frequency is specified as testing the inductance.
2. Rated D.C. current indicates the current when the inductance is 10% lower than its initial value at D.C. superposition,
or the current when at
∆
T=40°C, whichever is lower.
3. Operating temperature range: -30°C to +100°C.
4. Contact EEMPL for RoHS compliant version availability.
5. 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.
