Temperature rise is 55C in typical buck or boost circuits with the rated IDC current and reference ET applied to the inductor. 2. Total loss in the inductor is 80 mW (ROS 1) and 280 mW (ROS 2) for 55C temperature rise above ambient. 3. To estimate temperature rise in a given application, you must determine the total losses (copper losses + core losses) and apply the following formula: Temp Rise (C) = (Total Losses (mW)).833 * KO (from table) 4. To determine copper losses, calculate: Copper Loss (mW) = IDC2 x DCR 5. For core loss in mWatts, using frequency f (in Hz) and operating flux density B (in Gauss), calculate: Core Loss (mW) = k2 * f1.26 * B2.11 6. For flux density (B), calculate ET (V-sec) for the application, and multiply by ET10 factor from the table.
