Soldering
Recommended conditions
For reflow, use thermal conduction systems such as infrared radiation (IR) or hot blast. Vapor heat
transfer systems (VPS) are not recommended.
■Observe proper soldering conditions (temperature, time, etc.).
■Do not exceed the specified limits.
■Temperature measuring method: Measure temperature in assuming quantitative production,
by sticking the thermo-couple to the capacitor upper part with epoxy adhesives.
■Consult use for additional reflow restrictions.

General
Also see “Important notes” on page 11.
1 Aluminum electrolytic capacitors have a bi-polar structure. This is marked on the body of the
capacitor. A capacitor must not be mounted with reversed polarity. The application of an AC
or reverse voltage may cause a short circuit or damage the capacitor. Bi-polar capacitors
must not be used in AC applications, where the polarity may be reversed in the circuits or is
unknown.
2 The DC voltage applied to the capacitor terminal must not exceed its rated operating voltage,
as this will result in a rapid increase of the leakage current and may damage the capacitor. It
is recommended to operate the capacitor at 70–80% of its rated voltage to optimize its serv-
ice life.
3 The ripple current applied to the capacitor must be within the permitted range. An excessive
ripple current leads to impaired electrical properties and may damage the capacitor. Note that
the sum of the peak values of the ripple voltage and the DC operating voltage must not ex-
ceed the rated DC voltage.
4 Capacitors must be used within their permitted range of operating temperature. Operation at
room temperature optimizes their service life.
5 Capacitors with case diameter ≥8 mm are equipped with a safety vent. In capacitors fitted
with a lead or soldering lug, the safety vent is usually located at the base of the case. It needs
sufficient space around it to operate optimally. The following dimensions are recommended:
for case diameter d = 8 to 16 mm, more than 2 mm; for d =18 to 35 mm, more than 3 mm;
and for d = 42 mm or more, more than 5 mm.
6 Capacitors should not be mounted with the safety vent face down on the board. Do not locate
any wire or copper trace near the safety vent. Do not reverse the voltage, as this may result
in excess pressure and the leakage of electrolyte.
7 Gas is released through the safety vent when the pressure inside the capacitor is too high. A
gaseous liquid around the safety vent does not indicate a leakage of electrolyte.
8 The capacitor should be stored under conditions of normal temperature and in a non-acid,
non-alkali environment of normal humidity. Exposure to high temperatures, for example un-
der direct sunlight, will reduce its operating life. If the capacitor is stored in an environment
containing acids or alkalis, the solderability of the leads may be affected.
9 The leakage current of an aluminum electrolytic capacitor may increase after a long period
of storage. After such storage, the capacitor must be aged by applying the rated operating
voltage for 6–8 hours before use.
10 Manual soldering:
a Soldering must be performed within the specified conditions.
Bit temperature: 350 °C; application time of soldering iron: 3 seconds.
b Ensure that the soldering iron does not touch any part of the capacitor body.

Important notes at the end of this document.
11 Do not apply excessive force to the leads and terminals. Do not move the capacitor after sol-
dering it onto the PC board and do not carry the PC board by gripping the capacitor. Observe
the following rules to prevent undue stress to the capacitor:
a Do not tilt or bend the capacitor after soldering.
b Ensure that the terminal spacing matches the corresponding hole spacing on the PC
board.
12 The aluminum case is not insulated from the cathode. Do not place a conductor under the
aluminum capacitors on the PC board as this may cause a short circuit. The case and top of
capacitors used in switched mode power supplies have a high-voltage-resistant heat shrink
sleeve to ensure safe usage.
13 The leads of capacitors with a case diameter exceeding 14 mm cannot be used for fixing.

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, 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 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.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. Consequently,
we cannot guarantee that all products named in this publication will always be available. The
aforementioned does not apply in case of individual agreements deviating from the foregoing for
customer-specific products.
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 (ZVEI).
