Single-Ended Aluminum Electrolytic Capacitors – ESL, +105°C
Shelf Life
The capacitance, ESR and impedance of a capacitor will not change signicantly after extended storage periods, however,
the leakage current will very slowly increase.
KEMET's E aluminum electrolytic capacitors should not be stored in high temperatures or where there is a high level of
humidity. The suitable storage condition for KEMET's E aluminum electrolytic capacitors is +5 to +35°C and less than 75%
in relative humidity. KEMET's E aluminum electrolytic capacitors should not be stored in damp conditions such as water,
saltwater spray or oil spray. KEMET's E aluminum electrolytic capacitors should not be stored in an environment full of
hazardous gas (hydrogen sulphide, sulphurous acid gas, nitrous acid, chlorine gas, ammonium, etc.) KEMET's E aluminum
electrolytic capacitors should not be stored under exposure to ozone, ultraviolet rays or radiation.
If a capacitor has been stored for more than 18 months under these conditions and it shows increased leakage current,
then a treatment by voltage application is recommended.
Re-Age (Reforming) Procedure
Apply the rated voltage to the capacitor at room temperature for a period of one hour, or until the leakage current has fallen
to a steady value below the specied limit. During re-aging a maximum charging current of twice the specied leakage
current or 5 mA, whichever is greater, is suggested.
