General

Also see “Important notes” on page 9.

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.

Cautions and warnings

804/08

Please read Cautions and warnings and

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

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).

7. The trade names EPCOS, BAOKE, Alu-X, CeraDiode, CSSP, CTVS, DSSP, MiniBlue, MKK,
