THT POWER INDUCTORS
Toroid - Bare Coil Series
Notes from Tables
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.
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)

* (ΔB/2000)
