AC Motor Start Aluminum Electrolytic Capacitors

MS/MD, +60°C/+70°C

Overview

Applications

KEMET's MS/MD Series of aluminum electrolytic

capacitors are designed for intermittent 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 capacitors are 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

General approval notes:

• Valid for both ±10% and −0+25% tolerance.

• Valid for intermediate capacitance. Values in increments of 1 µF between 30 µF and 100 µF, and in increments of 5 µF between 100 µF and 125 µF.

• Approved duty cycles relate to 50 Hz, as per section 3.1.12.2 of IEC60252–2 operation at 60 Hz is also approved if the relative operation time is reduced

by 20%. For example a 50 Hz duty cycle with ED = 1.7% is also approved for 60 Hz with ED = 1.36%.

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) =

Environmental Compliance

All Part Numbers in this datasheet are Reach and RoHS compliant and Halogen-Free.

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 such as 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 worldwide and

make 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.

Due to customer requirements, there may appear additional markings such as lead-free (LF), or lead-free wires (LFW) on the

label.
