Ripple Current

Maximum ripple current specified at 120 Hz 105°C

No ripple current applied

Voltage

The sum of DC voltage and the peak AC voltage

must not exceed the rated voltage of the capacitor

No voltage applied

Performance

The following specifications will be satisfied when the capacitor is restored to 20°C:

Capacitance Change

Within ±20% of the initial value

Dissipation Factor

Does not exceed 200% of the specified value

Leakage Current

Does not exceed specified value

Shelf Life

The capacitance, ESR and impedance of a capacitor will not change significantly 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 specified limit. During re-aging a maximum charging current of twice the specified leakage

current or 5 mA, whichever is greater, is suggested.
