Notes:
1. The DCR is measured from point a to point b, as shown on the mechanical drawing.
2. Inductance is tested at 0.1Vrms, 1MHz.
3. The rated current as listed is either the saturation current or the heating current depending on which value is lower.
4. The saturation current, Isat, is the current at which the inductance of the component drops by 10% typical at an
ambient temperature of 25ºC.
5. The heating current is the DC current required to raise the component temperature by approximately 40ºC at ambient
temperature of 25ºC. For parallel connection, the heating current of this part is 40A. For series connection, the heating
current of this part is 20A.
6. Operating temperature range: -40ºC to +130ºC. 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 temperatures should be verified in the end application.
