Notes:
1. All test data is referenced to 23±3 °C and 45%RH to 70%RH ambient.
2. Test Instruments：3260B LCR Meter, 3265B Bias Current Source（100kHz,1V）
，EUCOL-U2516B
DC Low ohm meter.
3. Operating temperature range - 55 °C to + 125 °C（ambient + self-temp. rise）.
4. Isat: DC current (A) that will cause L
0
to drop approximately 30 %.
5. Idc: DC current (A) that will cause an approximate ΔT of 40 °C.
6. The part temperature (ambient + temp. rise) should not exceed 125 °C 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. The rated current as listed is either the saturation current or the heat rating current depending on
which value is lower.
