**:Inductance Tolerance 20%
Note 1.: All test data is referenced to 25℃ ambient.
Note 2.: Test Condition:1MHz, 1.0Vrms
Note 3.: Idc : DC current (A) that will cause an approximate △ T of 40℃
Note 4.: Isat : DC current (A) that will cause L0 to drop approximately 30%
Note 5.: Operating Temperature Range -55℃ to + 125℃
Note 6.: The part temperature (ambient + temp rise) should not exceed 125℃ under the worst case operating
conditions. Circuit design , component placement, PCB trace size and thickness, airflow and other cooling
provision all affect the part temperature. Part temperature should be verified in the end application.
Note 7.: The rated current as listed is either the saturation current or the heating current depending on which value
is lower.
