Test frequency is specified as the frequency for measuring the inductance. 2. Rated D.C. current indicates the value of the current when the inductance is 35% lower than its initial value or the current when temperature rising T=40 C at D.C. Superposition. o 3. Operating temperature range: -25C to +85C. 4. The part temperature (ambient temperature + temperature rise) should not exceed the upper limit of the operating temperature 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. 5.
