Idc ( A ) Saturation Current DC Amps. Isat ( A ) Typical Maximum Typical Maximum Typical Maximum * ：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 n ot exceed 125℃ under the worst case operating conditions. Circuit design, component placement, PC B trace size and thickness, airflow and other cooli ng 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 saturatio n current or the heating current depending on which value is lower.
