Product Brief 2011
Power Capacitors
MKK-DC / MKK-DCI (-H) / MKK-DC-R
Characteristics and
properties
High performance gas-impregnated capacitors offered for
applications with medium voltage from 1500 to 3000 V DC
and medium currents, with
clear advantages in terms of
lightness and reduced cost.
Oil-impregnated capacitors are
alternatives when applications
demand high operating temperature and currents, resulting
in critical heating that is more
effectively evacuated by oil.
This technology in oil is also
more suitable for applications
with high nominal voltages of
>1800 V DC and/or high ripple
voltages above 400 V RMS.
Polyurethane resin-filled capacitors are offered in low voltage
www.epcos.com
applications with high currents
due to their more simple construction with less components. The resin acts as insulator and heat conductor.
In those cases where due to
constraints in the application,
the design of choice as explained above is not advisable
or appropriate, a special
custom-made design with
another technology is possible.
Applications
• DC-voltage applications for
DC link
• Resonant filtering
• Frequency converters
Housing
• Rectangular non-magnetic
stainless steel case
• Ferric steel, aluminum

Power Capacitors
MKK-DC/MKK-DCI/MKK-DCI-H:
Mechanical considerations and construction
General description
The MKK-DC/MKK-DCI/MKK-DCI-H capacitors are
designed in rectangular cases made of austenitic
stainless steel. The cases are hermetically welded
and the surface is not painted. Fixing brackets and
bolts are mounted to fix the capacitor. Bolts are used
also for the ground connection.
Different types of terminals are available for the
terminal connections.
The capacitors should be exclusively handled by the
fixing brackets. In no case the terminals should be
used to lift the capacitor.
Capacitors will usually be mounted upright (terminals
on top), but can be mounted in any position keeping
a distance of 25 mm minimum between large facets,
to allow for thermal expansion and effective cooling.
Dimensions
The following table shows the available standard
dimensions. Deviations from these dimensions are
available upon request.
Tolerances are indicated in the drawings as well as the
maximum thermal expansions during normal operation
conditions.
The label is located centered to the length and 50 mm
from the top of the case.
Labeling: manufacturer (company logo), ordering code,
connection diagram, version, rated capacitance,
tolerance, weight, insulating voltage, IEC standard,
country of origin, month/year of manufacturing.

Terminals and connections
Standard terminals are available as shown below.
Brass bolts, tinned, with different metrics in male and
possibility of female connection, are available upon
request.
Insulation material of the terminal is Epoxy according to
CTI 600.
The following table shows the maximum continuous
currents acceptable (for a temperature increase in the
terminals of +15 °C), the maximum torque and the
contact surface of standard terminals.
Other specific options are available upon request.

in the drawing below. For heights lower than 500 mm,
the lower brackets are removed.
Upon request it is possible to substitute the fixing
brackets by bolts (only for heights lower than 500
mm).
Other specific options are available upon request.

MKK-DC-R:
Mechanical considerations and construction
General description
The MKK-DC-R capacitors are designed in aluminum
rectangular cases filled with resin.
Fixing brackets are available as shown below. For any
other options, please contact our local sales office.
The standard connection terminals are shown in the
drawing below. Otherwise brass bolts tinned with
male and possibility of female connection are
available upon request.
The capacitors should be exclusively handled by
fixing brackets. In no case, the terminals should be
used to lift the capacitor.
Capacitors will usually be mounted upright (terminals
on top), but can be mounted in any position keeping
a lateral space of 25 mm minimum.
