Environmental Compliance

As a leading global supplier of electronic components and an environmentally conscious company, KEMET continually

aspires to improve the environmental effects of our manufacturing processes and our finished electronic components.

In Europe (RoHS Directive) and in some other geographical areas such as China (China RoHS), legislation has been enacted

to prevent or otherwise limit the use of certain hazardous materials, including lead (Pb), in electronic equipment. KEMET

monitors legislation globally to ensure compliance and endeavors to adjust our manufacturing processes and/or electronic

components as may be required by applicable law.

For military, medical, automotive, and some commercial applications, the use of lead (Pb) in the termination is necessary

and/or required by design. KEMET is committed to communicating RoHS compliance to our customers. Information related

to RoHS compliance will be provided in data sheets and using specific identifiers on the packaging labels.

All KEMET power film capacitors are RoHS compliant.

Materials & Environment

The selection of raw materials that KEMET uses for the production of its electronic components is the result of extensive

experience. KEMET directs specific attention toward environmental protection. KEMET selects its suppliers according to

ISO 9001 standards and performs statistical analyses on raw materials before acceptance for use in manufacturing our

electronic components. All materials are, to the best of KEMET’s knowledge, non-toxic and free from cadmium; mercury;

chrome and compounds; polychlorine triphenyl (PCB); bromide and chlorinedioxins bromurate clorurate; CFC and HCFC;

and asbestos.

Dissipation Factor

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

temperature. For more information, refer to Performance Characteristics.

Sealing

Hermetically Sealed Capacitors

As the temperature increases, the pressure inside the capacitor increases. If the internal pressure is high enough, it can

cause a breach in the capacitor. Such a breach can result in leakage, impregnation, filling fluid, or moisture susceptibility.

Barometric Pressure

The altitude at which hermetically sealed capacitors are operated controls the capacitor's voltage rating. As the barometric

pressure decreases, the susceptibility to terminal arc-over increases. Non-hermetic capacitors can be affected by internal

stresses due to pressure changes. These effects can be in the form of capacitance changes, dielectric arc-over, and/or low

insulation resistance. Altitude can also affect heat transfer. Heat that is generated in an operation cannot be dissipated

properly, and high RI2 losses and eventual failure can result.
