My question is about the difference between the 6 cores stacked or two
stacks side by side.
For a ferrite choke with close-spaced turns, it does not matter if he
cores are together or separated. What matters is the number of turns and
the number of cores. The inductance increases with the square of the
number of turns, and in proportion to the number of cores. The
capacitance increases with the number of turns and with close spacing.
What you want is the lowest practical resonant frequency, and you can
use the measured data in my RFI tutorial as a guide. So for the lowest
possible resonant frequency you want more turns and more cores, tightly
