ccfl_man: it depends on the load, almost completely if its after a regulator
so if its for audio, you would do like, i dunno 100, 1k and 40k
if its a digital circuit, like 100k
above 100k you prob want to use other types of caps, ceramic and film, the electrolytics will work but not well, not to spec

they were better or worse
for example, panasonic wont always list ESR
impedance at high frequency isnt ESR
its just an indicator or how much the cap sucks at being a cap at higher frequency, electrolytics are usually spec'd for like 100Hz operation
because they didnt both to calc ESR when they datasheets list a delta tan
check panasonic FC series
if its too good, try NHG or M series
if its not good enough, try panasonic FM
if theyre too expensive, look for chemicon equivalent series

3rd post
reza____: wtf add a watchdog or psu/reset sequencing circuit
where are you adding delay?
in some sort of non volatile config register, or in code?
than yeah sounds fine
ccfl_man: a lot of times you can derive rough ESR from the max operating temp, too

wtf ESR .1 to 1 ohm
why do you need it in that range?

omg the guy put the rice on the left and the beans on the right this time!?
he never does that i wonder what it means

and in audio thats not a joke btw =\
