:* 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 Lo 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 worse 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.
