AC Motor Start Aluminum Electrolytic Capacitors
MS/MD Series, +60ºC/+70°C
Overview
Applications
KEMET's MS/MD Series of aluminum electrolytic capacitors are
designed for itermittent duty only and capable of withstanding
the AC voltage applied to the motor during starting. The
capacitor construction is comprised of either double anode or
O-style (double anode and floating cathode) windings, which
are housed in a molded plastic case. KEMET's MD Series is
VDE approved to IEC 60252-2 for the defined ratings.
KEMET's MS/MD Series is a range of aluminium electrolytic
capacitors specifically designed for AC operation which helps
to start the motor by providing a leading current to the auxiliary
winding. The capacitor is not permanently connected to the
winding of the motor and is usually switched off automatically
after starting.
Benefits
• Intermittent AC motor starting
• 6.3 mm double amp tags (quick connect types)
• VDE approved to IEC 60252–2

Duty Cycle
The standard rating is 1.67% or 1/60th full time and corresponds to a maximum duty of 20 starts, each of three seconds duration
per hour. It is expressed as 3/1.67 (a 3 minute cycle with 1.67% duration during which the capacitor may be energized). If the same
capacitor is to be used for a duty cycle of 60 starts per hour the cycle duration will be 1 minute. The operation time per cycle will then
have to be reduced to 1.67% of 1 minute (i.e. 1 second). Alternative duty cycles are available on request.
Presence of Run Capacitor
When the motor is fitted with both starting and run capacitors, consideration should be given to fitting of the appropriate discharge
resistor to the starting capacitor. This is to protect the run capacitor from damage through discharge of the starting capacitor.
Container Form
Cylindrical mouldings, meeting creepage and clearance distances, according to IEC 60335–1 and flammability ratings according to
UL94–V1.

Discharge Resistors
A discharge resistor may be fitted 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/Rated Capacitance (µF)

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 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 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.
