Notes from Tables
Estimated Temperature Rise:
1. 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.
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)
3. To determine the inductance of a component at a different operating current, use the graph below for the appropriate material type.
CopperLoss = Irms2 * DCR_Typical (mΩ) / 1000
DCR_Typical (mΩ) = .85 * DCR_Max(from table)
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.
CoreLoss = K2 * (Freq_kHz)K3 * (∆B/2000)K4
∆B = K1 * Volt-µsec
