Hi there,

hope this is the right newsgroup:

Can I replace a dead condenser (2200 mueF, 6,3V) with a 3000 mueF, 10V
one? What are the limitations in this case?

Thanx in advance...

Georg

Probably, since it's probably just filtering, but without seeing the circuit
it's impossible to sure. It's worth a try. You should just have a bit more
filtering with a bit more head-room on the voltage front - no problem.

If it's just a regular power supply, then it should be okay.  But if
it's a switching power supply, then it might have to be low ESR, which 
means that it has low losses, especially at switching frequencies.

PUNCTUATION - Apostrophe
Incorrect uses: (i) the apostrophe must not be used with a plural
where there is no possessive sense, as in ~tea's are served here~;
(ii) there is no such word as ~her's, our's, their's, your's~.

Confusions: it's = it is or it has (not 'belonging to it'); correct
uses are ~it's here~ (= it is here); ~it's gone~ (= it has gone);
but ~the dog wagged its tail~ (no apostrophe).

Assuming the capacitor is in a non critical area, eg as a filter cap in a
supply line, you could use the 3000uF cap instead. The things to watch out
for are physical size (obviously) and temperature rating, make sure that if
the original is a 105 degree C part (it will be marked as such, if not it is
85 degree C), the replacement has an equal or better temperature rating.
