Note 2.： Test Condition:100KHz, 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, PWB 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.
