(1). Inductance tolerance: M±20% / N±30% tested at 0.25V, 0ADC and 25℃
(2). DCR measured at 25℃.
(3). The DC current at which the inductance decreases by 20% from its initial value.
(4). The DC current that results in a 40℃ temperature rise from 25℃ ambient
(*). Part temperature (ambient + temp rise) should not exceed 125℃ under worst case operating conditions. Circuit design, component
placement, PCB trace size and thickness, airflow and other cooling provisions may affect the temperature of the part. Part temperature
should be verified in the end application.
