Environmental Compliance
As an environmentally conscious company, KEMET is working continuously to improveme the environmental effects of both
our capacitors and their production.
In Europe, due to the RoHS Directive, and in some other geographical areas such as China, legislation has been put in place
to prevent the use of some hazardous materials, including lead (Pb) in electronic equipment. All products in this catalog are
produced to help our customers' obligations to guarantee their products to fulll these legislative requirements. The only
material of concern in our products has been lead (Pb), which has been removed from all designs to fulll the requirement of
containing less than 0.1% of lead in any homogeneous material.
KEMET will closely follow any changes in legislation on a global basis and make any necessary changes to its products
whenever needed.
Some customer segments including medical, defense and automotive electronics may still require the use of lead in
electrode coatings. To clarify the situation and distinguish products, the following symbols are used on the packaging labels
for RoHS compliant and Pb-free capacitors.
Because of customer requirements, additional markings such as "LF" for lead-free or "LFW" for lead-free wires may appear
on the packaging label.
Materials & Environment
The selection of materials used by KEMET for the production of capacitors is the result of extensive experience and
constant attention to environmental protection. KEMET selects its suppliers according to ISO 9001 standards and carries out
statistical analysis on the materials purchased before acceptance. All materials are, to the company's present knowledge,
non-toxic and free from cadmium, mercury, chrome and compounds, polychlorine triphenyl (PCB), bromide and chlorine
dioxins bromurate clorurate, CFC and HCFC, and asbestos.
Green Products
All KEMET power lm products are ROHS Compliant.
Insulation Resistance
When the capacitor temperature increases, the insulation resistance decreases. This is due to increased electron activity.
Low insulation resistance can also be the result of moisture trapped in the windings, caused by a prolonged exposure to
excessive humidity.
