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, like 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 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.

All KEMET power lm products are RoHS Compliant.

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 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.

Dissipation Factor

Dissipation factor is a complex function involved with the inefciency of the capacitor. The tgδ may change up and down

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