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 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 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.

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.

Sealing

Hermetically Sealed Capacitors

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

cause a breach in the capacitor which can result in leakage, impregnation, lling uid or moisture susceptibility.

Resin Encased/Wrap & Fill Capacitors

The resin seals on resin encased and wrap and ll capacitors will withstand short-term exposure to high humidity

environments without degradation. Resins and plastic tapes will form a pseudo-impervious barrier to humidity and

chemicals. These case materials are somewhat porous and through osmosis can cause contaminants to enter the capacitor.

The second area of contaminated absorption is the lead-wire/resin interface. Since resins cannot bond 100% to tinned wires,

there can be a path formed up to the lead wire into the capacitor section. Aqueous cleaning of circuit boards can aggravate

this condition.

Barometric Pressure

The altitude at which hermetically sealed capacitors are operated controls the voltage rating of the capacitor. 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. This can be in the form of capacitance changes or dielectric arc-over as well

as low insulation resistance. Heat transfer can also be affected by altitude operation. Heat generated in operation cannot be

dissipated properly and can result in high RI2 losses and eventual failure.

Radiation

Radiation capabilities of capacitors must be taken into consideration. Electrical degradation in the form of dielectric

embitterment can take place causing shorts or opens.
