I am using the Fairchild FSCQ series and I am shocked that nowhere is there any guide for sizing the bead on the drain. The frequency range is 24kHz min. to (looks like) 90kHz.

There is also another one on one of the outputs, but that seems to be straightforward, except, according to them, the corner frequency cannot be too low or it may affect stability. I assume that means it must be above the 24kHz.

At any rate, my intuition tells me that board layout will affect the sizing of Bead 101 in the diagram, and since they have no way of telling how the board will be designed, have left out the value.

Bead L202 on a 140v., 6A load, was sized at 5uH, 3A. Noteworthy is that is referred to as a L202, and not just "Bead" as in 101.

Anyway, the question is, does anyone have any ideas as to how to size Bead 101?
