Environmental Compliance

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

both our capacitors and the production of them.

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, like Lead (Pb), in electronic equipment. All products in this catalog are produced to help our customers'

obligations to guarantee their products to 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 like 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 like LF = Lead Free or LFW = Lead Free Wires on the 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, PCB (Polychlorine Triphenyl), Bromide and Chlorine Dioxins Bromurate Clorurate, CFC and HCFC

and Asbestos.

Green Products

All KEMET power film 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.

Dissipation Factor

Dissipation factor is a complex function involved with the inefficiency of the capacitor. The tgδ may change up and down with increased

temperature. For more information, please refer to Performance Characteristics.
