Surface Mount Aluminum Electrolytic Capacitors – EDH Series, +105°C
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 world wide 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.

Leakage Current
The following specifications will be satisfied when the capacitor is restored to 20°C:
Can Ø = 4 – 6.3 mm within ±25% of the initial value
Can Ø = 8 – 16 mm within ±20% of the initial value
Does not exceed 200% of the specified value
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-series 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-series aluminum electrolytic capacitors is +5 to +35°C and less than 75% in
relative humidity.
KEMET's E-series aluminum electrolytic capacitors should not be stored in damp conditions such as water, saltwater spray or
oil spray.
KEMET's E-series 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-series 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.

Application and Operation Guidelines
Electrical Ratings:
Capacitance (ESC)
Simplified equivalent circuit diagram of an electrolytic capacitor
Thecapacitivecomponentoftheequivalentseriescircuit(EquivalentSeriesCapacitanceESC)isdeterminedbyapplyingan

Capacitance Change vs. Temperature
(typical value)
Capacitance Change (%)
Temperature Dependence of the Capacitance
Capacitance of an electrolytic capacitor depends upon
temperature:withdecreasingtemperaturetheviscosity
oftheelectrolyteincreases,therebyreducingits
conductivity.
Capacitance will decrease if temperature decreases.
Furthermore,temperaturedriftscausearmature
dilatationand,therefore,capacitancechanges(upto20%
dependingontheseriesconsidered,from0to80°C).This
