* ：If you require another part number please contact with us.
**：Inductance Tolerance 20%
Note 1.： All test data is referenced to 25℃ ambient.
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, 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.
