Axial Aluminum Electrolytic Capacitors – PEG124, +105°C and +125°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 products are particularly stable and allow a shelf life in excess of ten years
at 40°C. See sectional specication under each product series for specic data.
Failure Rate
Estimated eld failure rate: ≤ 1.0 ppm (failures per year/produced number of capacitors per year).
The expected failure rate for this capacitor range is based on eld experience for capacitors with structural similarity.
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 fulll
these legislative requirements. The only material of concern in our products has been lead (Pb), which has been removed
from all designs to fulll 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.
Due to customer requirements, there may appear additional markings such as LF = Lead-Free or LFW = Lead-Free Wires on
the label.
