(2) Operating and Storage temperature range -40 C to +125 C. (3) DC current (A) that will cause an approximate T of 40 C. (4) DC current (A) that will cause L to drop approximately 20 %. 0 (5) The part temperature (ambient + temp. rise) should not exceed 125 C under worst case operating conditions. Circuit design, component placement, PWB trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application.
