Useful life1)
For useful life calculations, please use our web-based "AlCap Useful Life Calculation Tool", which
can be found on the Internet under the following link:
www.tdk-electronics.tdk.com/alcap
The AlCap Useful Life Calculation Tool provides calculations of useful life as well as additional data
for selected capacitor types under operating conditions defined by the user.
In addition, it is possible to calculate useful life expectancies based on temperatures measured by
the user in the application.

Cautions and warnings

Personal safety

The electrolytes used have been optimized both with a view to the intended application and with
regard to health and environmental compatibility. They do not contain any solvents that are de-
trimental to health, e.g. dimethyl formamide (DMF) or dimethyl acetamide (DMAC). Furthermore,
some of the high-voltage electrolytes used are self-extinguishing.
As far as possible, we do not use any dangerous chemicals or compounds to produce operating
electrolytes, although in exceptional cases, such materials must be used in order to achieve spe-
cific physical and electrical properties because no alternative materials are currently known.
We do, however, restrict the amount of dangerous materials used in our products to an absolute
minimum.
Materials and chemicals used in our aluminum electrolytic capacitors are continuously adapted in
compliance with the TDK Electronics Corporate Environmental Policy and the latest EU regula-
tions and guidelines such as RoHS, REACH/SVHC, GADSL, and ELV.
MDS (Material Data Sheets) are available on our website for all types listed in the data book.
MDS for customer specific capacitors are available upon request.
MSDS (Material Safety Data Sheets) are available for our electrolytes upon request.
Nevertheless, the following rules should be observed when handling aluminum electrolytic capa-
citors: No electrolyte should come into contact with eyes or skin. If electrolyte does come into con-
tact with the skin, wash the affected areas immediately with running water. If the eyes are affected,
rinse them for 10 minutes with plenty of water. If symptoms persist, seek medical treatment. Avoid
inhaling electrolyte vapor or mists. Workplaces and other affected areas should be well ventilated.
Clothing that has been contaminated by electrolyte must be changed and rinsed in water.

Display of ordering codes for TDK Electronics products

The ordering code for one and the same product can be represented differently in data sheets, data
books, other publications, on the company website, or in order-related documents such as shipping
notes, order confirmations and product labels. The varying representations of the ordering codes
are due to different processes employed and do not affect the specifications of the respective pro-
ducts.

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.

Important notes

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.
