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

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 requirements that are
often placed on our products in the areas of application concerned. We nevertheless 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 we are 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 a 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 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 requiring a very high level of
operational safety and especially in customer applications in which the malfunction or failure of an
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 suitable 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 an 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 publication
may contain substances subject to restrictions in certain jurisdictions (e.g. because they are
classed as hazardous). Useful information on this will be found in our Material Data Sheets on the
Internet (www.tdk-electronics.tdk.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. Consequently, we
cannot guarantee that all products named in this publication will always be available. The
aforementioned does not apply in the case of individual agreements deviating from the foregoing for
customer-specific products.
6. Unless otherwise agreed in individual contracts, all orders are subject to our General Terms and
Conditions of Supply.
7. Our manufacturing sites serving the automotive business apply the IATF 16949 standard. The
IATF certifications confirm our compliance with requirements regarding the quality management system
in the automotive industry. Referring to customer requirements and customer specific requirements
(“CSR”) TDK always has and will continue to have the policy of respecting individual agreements. Even
if IATF 16949 may appear to support the acceptance of unilateral requirements, we hereby like to
emphasize that only requirements mutually agreed upon can and will be implemented in our
Quality Management System. For clarification purposes we like to point out that obligations from IATF
16949 shall only become legally binding if individually agreed upon.
