The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range. 2. The rated current is the current that will cause the temperature of the part to increase by 40°C with 3.6 volt * µsec across the component and 100LFM of forced air cooling. 3. To determine the inductance of a component at a different operating current, use the graph below for the appropriate material type. 4. In high volt-µsec applications additional heating may occur due to core losses in the inductor which may necessitate derating the current in order to limit the temperature rise of the component. In order to determine the approximate total losses (or temperature rise) of the component in particular applications, the following formulas can be used. Estimated Temperature Rise: Trise = AirFlowFactor * K5 * (Coreloss(W) + Copperloss(W)) .833 (C) Where AirFlowFactor = 1 (no air flow), 0.53 (100LFM), 0.39 (200LFM), 0.35 (300LFM), 0.30 (400LFM) CopperLoss = Irms 2 * DCR_Typical (mΩ) / 1000 DCR_Typical (mΩ) = .85 * DCR_Max(from table) CoreLoss = K2 * (Freq_kHz)K3 * (ΔB/2000)K4 ΔB = K1 * Volt-µsec Notes from Tables /MT73/MT110/MT100/MT117/MT99/MT116/MT97/MT110/MT99/MT101/MT32/MT118/MT115/MT32/MT77/MT97/MT103/MT110/MT101/MT116/MT105/MT122/MT105/MT110/MT103/MT32/MT70/MT111/MT114/MT99/MT101 /MT48 /MT50/MT48 /MT52/MT48 /MT54/MT48 /MT56/MT48 /MT49/MT48/MT48 /MT49/MT50/MT48 /MT48/MT49 /MT48/MT50 /MT48/MT51 /MT48/MT52 /MT48/MT53 /MT48/MT54 /MT48/MT55 /MT48/MT56 /MT48/MT57 /MT48/MT49 /MT48 /MT48 /MT49 /MT49 /MT48 /MT49 /MT50 /MT48 /MT72/MT45/MT68/MT67/MT32/MT40/MT79/MT101/MT41/MT32/MT61/MT32/MT72/MT49/MT32/MT42/MT32/MT67/MT117/MT114/MT114/MT101/MT110/MT116/MT32/MT40/MT65/MT41 /MT80/MT101/MT114/MT99/MT101/MT110/MT116/MT32/MT111/MT102/MT32/MT73/MT110/MT116/MT105/MT97/MT108/MT32/MT73/MT110/MT100/MT117/MT99/MT116/MT97/MT110/MT99/MT101 /MT77/MT97/MT116/MT101/MT114/MT105/MT97/MT108/MT32/MT45/MT56/MT47/MT57/MT48/MT32/MT40/MT51/MT53/MT181/MT41 /MT77/MT97/MT116/MT101/MT114/MT105/MT97/MT108/MT32/MT45/MT49/MT56/MT32/MT40/MT53/MT53/MT181/MT41 /MT77/MT97/MT116/MT101/MT114/MT105/MT97/MT108/MT32/MT45/MT53/MT50/MT32/MT40/MT55/MT53/MT181/MT41 THT POWER INDUCTORS Toroid - Bare Coil Series /MT67 /MT77/MT65/MT88 /MT65 /MT77/MT65/MT88 /MT68 /MT78/MT79/MT77 /MT69 /MT77/MT65/MT88 /MT66 /MT77/MT65/MT88 /MT70 /MT78/MT79/MT77 Mechanical Schematic Dimensions (in/mm) Dimensions: Inches mm /MT49 /MT50 Part No. A B C D E F 20,50 9,50 19,00 3,20 2,50 9,00 20,50 10,50 19,00 3,20 2,68 9,00 15,90 8,80 13,80 3,30 1,30 7,60 10,20 16,80 3,80 1,30 7,60 15,90 8,80 13,80 3,30 1,30 7,60 PA0430L .874 .374 N/A .250 N/A .245 22,20 9,50 6,40 6,20 23,00 12,50 23,00 3,30 1,40 7,60 14,50 7,00 14,50 3,20 1,05 7,00 15,30 8,20 14,10 4,00 1,20 6,40 16,00 9,50 16,00 3,20 1,60 7,50 15,50 8,30 3,30 1,10 7,60 22,20 9,50 6,40 1,40 6,10 24,90 11,20 24,90 6,40 1,40 7,90
