All test data is referenced to 25

Test Condition 1MHz, 1.0Vrms

Idc : DC current (A) that will cause an approximate

Isat : DC current (A) that will cause L0 to drop approximately 30%

Operating Temperature Range -55 to + 125

The part temperature (ambient + temp rise) should not exceed 125

ambient.

T of 40

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.
