aluminum electrolytic capacitors vary by tempe-
rature as follows. These variations are temporary
and recover when the temperature goes back
(except for the case of characteristic deterioration
because of high temperatures over a long time).
Note that using capacitors over the upper category
temperature increases leakage current, resulting in
a short and destruction.
Be careful of the capacitor temperature considering
not only the ambient temperature where the
equipment is placed and the temperature inside the
equipment but also radiation heat from the heating
