Single-Ended Conductive Polymer Aluminum Solid Electrolytic Capacitors

A750 Series, 105°C

Shelf Life and Re-Ageing

• KEMET's conductive polymer aluminum solid 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 conductive polymer aluminum solid electrolytic capacitors is +5 to +35ºC and

less than 75% in relative humidity.

• KEMET's conductive polymer aluminum solid electrolytic capacitors should not be stored in damp conditions such as

water, saltwater spray or oil spray.

• KEMET's conductive polymer aluminum solid 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 conductive polymer aluminum solid electrolytic capacitors should not be stored under exposure to ozone,

ultraviolet rays or radiation.

The capacitance, ESR and impedance of a capacitor will not change significantly after extended storage periods, however the

leakage current will very slowly increase.

If a capacitor is stored for a long period of time, the leakage current must be verified. If the leakage current is superior to the

value listed in this catalog, the capacitors must be reformed.

Re-age (Reforming) Procedure

Apply the rated DC voltage to the capacitor at 105°C for a period of 120 minutes through a 1 kΩ series resistor.

Environmental Compliance

As an environmentally conscious company, KEMET is working continuously with improvements concerning the environmental

effects of both our capacitors and their production. In Europe (RoHS Directive) and in some other geographical areas like

China, legislation has been put in place to prevent the use of some hazardous materials, such as lead (Pb), in electronic

equipment. All products in this catalog are produced to help our customers' obligations to guarantee their products and fulfill

these legislative requirements. The only material of concern in our products has been lead (Pb), which has been removed

from all designs to fulfill the requirement of containing less than 0.1% of lead in any homogeneous material. KEMET will

closely follow any changes in legislation worldwide and makes any necessary changes in its products, whenever needed.

Some customer segments such as medical, military and automotive electronics may still require the use of Lead in electrode

coatings. To clarify the situation and distinguish products from each other, a special symbol is used on the packaging labels

for RoHS compatible capacitors.

Because of customer requirements, there may appear additional markings such as LF = Lead-free, or LFW = Lead-free wires

on the label.
