A good rule of thumb is to have at least a 100 to 1 ratio between cap values. Why? Because the self resonance of the cap, related to value, changes as the square root of the value, so 100 to 1 in value is 10 to one in resonance range. Less separation means interaction between the caps. It can be shown with a computer simulation.

- Very interesting. I wonder why c-j uses bypass-cap values as high as 15%... - jeffreybehr 09:51:14 04/16/07 (0)
