Capacitors with heat sink mounting (M607, M657)
As a large amount of heat is dissipated through the base of the case, the use of a heat sink connected to the capacitor base is the most efficient cooling method. For heat-sink mounting we offer
a special optimized version of high-voltage capacitors with screw terminals in order to ensure an
optimal heat transfer between the base of the case and the heat sink. The special design comprises:
Two thermal pads at the base. The first one (thickness 0.5 mm) closes the air gap at the base
in the area which is not covered by the insulating sleeve and the second one (thickness
0.2 mm) ensures the electrical insulation of the case.
Minimized tolerance (±0.35 mm) of the overall length l1 of the capacitor to avoid unwanted mechanical forces on the terminals particularly when several capacitors are mounted between
heat sink and bus bar.
Case with extra groove near the base for ring clamp mounting (recommended accessory
B44030A0165-A0190B). The clamp ensures an optimal pressing of the case to the heat sink.

Insulated base (M608, M658)
Length l and l1 increase by +0.5 mm for types with threaded stud
and insulated base. All other dimensions of the capacitor are
identical with those of standard capacitors. Please refer to the table
"Dimensions and weights".
PAPR terminal style (M650, M657, M658)
An aluminum electrolytic capacitor is a polar component that needs strictly to be mounted under
correct polarity. With our PAPR terminal style (Protection Against Polarity Reversal) we offer an
optional mechanical feature in addition to the visual polarity marking on the cover disk and the
sleeve, which prevents from mounting in reverse polarity.
The non-circular shape of the terminals and their arrangement perpendicular to each other enables the user to definitely prevent wrong mounting with respect to polarity (Poka Yoke).

Mounting instructions
Insulated mounting with washer and cap nut (for capacitors with threaded stud and without insulated base):
Mounting stud has the same potential as the negative terminal.
Attention must be paid on any relevant regulations (e.g. VDE, BSA or UL).
Ring clip mounting
Ring clips are primarily used for upright mounting of screw terminal and photoflash capacitors.
The ring clips are corrosion protected and are RoHS-compatible.
It is recommended to insert an additional insulating strip between capacitor and ring clip to avoid
any risk of damage due to edges from the clip. The strip is included in delivery. For ordering code,
see the following table. Attention must be paid to any relevant regulations (e.g. VDE, BSA or UL).

Clamp mounting
Screw terminal capacitors without threaded stud and with a diameter ≥ 64.3 mm can also be
mounted with ring clamps. Clamp mounting offers the following advantages:
Optimum heat transfer between capacitor base and board due to pressure contact
High vibration resistance
Electrically insulated material
Dimensional drawing
1)
Length of screw depends on application.
The screws have to be tightened uniformly and crosswise until the fixing part rests flatly on the
board.
3)
Tubular rivets included in delivery package.
2)
General hints for mounting: If required, the four fixation parts can be cut out from the common
carrier ring and mounted separately.

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
detrimental 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
specific 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 regulations 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
capacitors: No electrolyte should come into contact with eyes or skin. If electrolyte does come
into contact 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.

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 lifesaving 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.
