Hi,

I have been asked to sprinkle 6.8 uF tantalum or electrolytic capacitors
evenly around the PC board of a new design.

As usual, I have the 0.1 uF 805 ceramics at the power pins of chips and a
bulk storage cap. of 47 uF where power enters. The board is 3x4 inches, has
a few chips, slow edge rates. Mainly RS-232 (up to 1 mb/s) and the
internals of a PLD clocked at 16 MHz.

Can anyone tell me what the benefit of these 6.8 tantalums sprinkled around
would be?

Thanks,
Shayle
