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.
