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.
