Re: Toshiba vertical IC caps?

I've been looking at caps at various web pages and am going cross-eyed.
What's up with the different color of these caps in question? Is it just
a certain brand using a different color? To replace caps, is there
anything to know other than match the "uf" and the voltage ... and of
course, install them with the polarity correct? I thought I read
somewhere about being able to go, somewhat, "over size" with the voltage
... or did I dream that?


The color is arbitrary, depends on the brand, manufacturing line, date,
etc, it's just coincidence that most of the caps in the vertical area are
reddish.

You want to match the uF rating, voltage can go higher, but I would try to
keep it within 200% of the original rating, if you go too high the ESR
tends to rise as well. Even the uF rating is often not critical at all,
but don't substitute that unless you know what you're doing.

OK, and what about the temperature rating? Some are 105 C and others are 85
C. On this web page they are all 85 C. Are they OK to use where the old ones
were 105?
