MKV AC Capacitors

Damping, Commutating

B25834

Features

■

High dielectric strength       

■

High peak-current capability

Applications

■

For damping and commutating in
the medium frequency range

■

For general AC applications

Construction

■

Self-healing

■

Plastic dielectric

■

Oil-impregnated tubular windings (no PCB)

■

Metal-sprayed end faces ensure reliable contacting

■

Cylindrical aluminum case

■

Plastic or ceramic lead-throughs

■

Mounting bolts M8 or M12

Terminals

■

Screw terminals M10

■

Tab connectors 6.3 mm

■

Dual tab connectors 6.3 mm and 9.5 mm

Mounting

■

If the vibration stress is 

≤

 5

g

 and the capacitors are 

≤ 

60 mm

in diameter and 

≤ 

160 mm in height, the bolt is used for mounting.

Grounding

■

Mounting bolts for grounding in accordance with VDE 0100

■

Grounding identification in accordance with DIN 40 011

Overpressure disconnector (mechanical)

When the overpressure disconnector responds,
the capacitor extends by up to 8 mm.
So leave sufficient space above the terminals when mounting the capacitor.

Individual data sheets

Individual data sheets contain detailed specification incl. thermal data. 
Upon request, these data sheets are available for each capacitor type.

Cautions and warnings

Safety

■

In case of dents of more than 1 mm depth or any other mechanical damage, capacitors must not
be used at all. This applies also in cases of oil leakage.

■

Electrical or mechanical misapplication of capacitors may be hazardous. Personal injury or prop-
erty damage may result from bursting of the capacitor or from expulsion of oil or melted material
due to mechanical disruption of the capacitor.

■

Ensure good, effective grounding for capacitor enclosures.

■

Observe appropriate safety precautions during operation (self-recharging phenomena and the
high energy contained in capacitors).

■

Handle capacitors carefully, because they may still be charged even after disconnection.

■

The terminals of capacitors, connected bus bars and cables as well as other devices may also
be energized.

■

Follow good engineering practice.

■

Failure to follow cautions may result, worst case, in premature failures, bursting and fire.

Thermal load

After installation of the capacitor it is necessary to verify that maximum hot-spot temperature is not
exceeded at extreme service conditions (see www.epcos.com/thermal_design).

Mechanical protection

The capacitor has to be installed in a way that mechanical damages and dents in the aluminum can
are avoided.

Storage and Operating Conditions

Do not use or store capacitors in corrosive atmosphere especially where chloride gas, sulfide gas,
acid, alkali, salt or the like are present. In dusty environments, regular maintenance and cleaning
especially of the terminals is required to avoid conductive path between phases and/or phases and
ground.

Overpressure disconnector

To ensure full functionality of an overpressure disconnector, the following must be observed:

■

The elastic elements must not be hindered, i.e.
– connecting lines must be flexible leads (cables),
– there must be sufficient space (minimum 12 mm) above the connections for expansion of the

overpressure disconnector,

– folding crimps must not be retained by clamps.

■

Stress parameters of the capacitor must be within the IEC61071 specification.

Service life expectancy

Electrical components do not have an unlimited service life expectancy; this applies to self-healing
capacitors too. The maximum service life expectancy may vary depending on the application the
capacitor is used in.

Important notes

The following applies to all products named in this publication:
1. Some parts of this publication contain 

statements about the suitability of our products for

certain areas of application

. These statements are based on our knowledge of typical require-

ments that are often placed on our products in the areas of application concerned. We neverthe-
less expressly point out 

that such statements cannot be regarded as binding statements

about the suitability of our products for a particular customer application.

 

As a rule, EPCOS is either unfamiliar with individual customer applications or less familiar with
them than the customers themselves. For these reasons, it is always ultimately incumbent on the
customer to check and decide whether an EPCOS product with the properties described in the
product specification is suitable for use in a particular customer application.

2. We also point out that

 in individual cases, a malfunction of passive electronic components

or failure before the end of their usual service life cannot be completely ruled out in the
current state of the art, even if they are operated as specified.

 In customer applications re-

quiring a very high level of operational safety and especially in customer applications in which the
malfunction or failure of a passive electronic component could endanger human life or health
(e.g. in accident prevention or life-saving systems), it must therefore be ensured by means of suit-
able design of the customer application or other action taken by the customer (e.g. installation of
protective circuitry or redundancy) that no injury or damage is sustained by third parties in the
event of malfunction or failure of a passive electronic component.

3.

The warnings, cautions and product-specific notes must be observed

.

4. In order to satisfy certain technical requirements, 

some of the products described in this pub-

lication may contain substances subject to restrictions in certain jurisdictions (e.g. be-
cause they are classed as “hazardous”)

. Useful information on this will be found in our Material

Data Sheets on the Internet (www.epcos.com/material). Should you have any more detailed
questions, please contact our sales offices.

5. We constantly strive to improve our products. Consequently, 

the products described in this

publication may change from time to time

. The same is true of the corresponding product

specifications. Please check therefore to what extent product descriptions and specifications
contained in this publication are still applicable before or when you place an order.
We also 

reserve the right to discontinue production and delivery of products

. Consequent-

ly, we cannot guarantee that all products named in this publication will always be available. 

6. Unless otherwise agreed in individual contracts, 

all orders are subject to the current version

of the “General Terms of Delivery for Products and Services in the Electrical Industry”
published by the German Electrical and Electronics Industry Association
