Figure 1 shows the rod permeability as a function of the length to diameter ratio for the six materials available
in rods.
Figures 3, 4 and 5 illustrate typical temperature behavior of wound rods. Wound rods in 33 and 77 material yield
the best temperature stable inductors, see Figure 4. Both show a typical inductance change of < 1% over the
–40 to 120 C temperature range. The parts have a L/D ratio of 8.1. Lower ratios will change less. This is shown
in detail in Figure 5 for the same 52 material but with the L/D ratio as the parameter. A lower ratio means a lower
rod permeability but with improved temperature stability.
Wound Rod Inductance Calculations.
To calculate the inductance of a wound rod the following formula can be used.
Where: K = Inductance modifier
