Test Conditions
- All test data is referenced to 25 ambient.
- Test Condition: 1MHz, 1.0Vrms.
- Irms: DC current (A) that will cause an approximate T of 40.
- Isat: DC current (A) that will cause L0 to drop approximately 30%.
- Operating Temperature Range: -55 to +125.
- The part temperature (ambient + temp rise) should not exceed 125 under the worst case operating conditions. Part temperature should be verified in the end application.
- The rated current as listed is either the saturation current or the heating current depending on which value is lower.
