* ：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:1MHz, 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.
