AC Motor Start Aluminum Electrolytic Capacitors – MS/MD Series, +60ºC/+70°C
Discharge Resistors
A discharge resistor may be tted to a motor start capacitor to prevent electrical overstress of the capacitor and/or for
safety reasons. In accordance with IEC 60252, the resistor value should be such that it reduces the voltage on the capacitor,
from the line voltage to less than 50 V within 60 seconds. The resistor value may be approximated as follows: R(kOhms) = T/

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 fulll
these legislative requirements. The only material of concern in our products has been lead (Pb), which has been removed
from all designs to fulll 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.
