The temperature of the component (ambient plus temperature rise) Estimated Temperature Rise: must be within the stated operating temperature range833 Trise = AirFlowFactor * K5 * (Coreloss(W) + Copperloss(W)) (C) 2. The rated current is the current that will cause the temperature Where of the part to increase by 40C with 3.6 volt * sec across the AirFlowFactor = 1 (no air flow), 0.53 (100LFM), 0.39 (200LFM), 0.35 component and 100LFM of forced air cooling. (300LFM), 0.30 (400LFM) 3. To determine the inductance of a component at a different operating 2 CopperLoss = Irms * DCR Typical (m) / 1000 current, use the graph below for the appropriate material type. DCR Typical (m) = .85 * DCR Max(from table) 4. In high volt-sec applications additional heating may occur due to K3 K4 core losses in the inductor which may necessitate derating the CoreLoss = K2 * (Freq kHz) * (B/2000) current in order to limit the temperature rise of the component. In B = K1 * Volt-sec order to determine the approximate total losses (or temperature rise) of the component in particular applications, the following formulas can be used.
