Operating temperature range - 55 C to + 125 C 3. Idc(A):DC current (A) that will cause an approximate ΔT of 4 C(reference ambient temperature is 25 C ) 4. Isat(A):DC current (A) that will cause L to drop approximately 3 % 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.
