Cautions and warnings  
How to select ceramic capacitors  
Remember the following when selecting ceramic capacitors:  
1. Ceramic capacitors that must fulfill high quality requirements must be qualified based on  
AEC-Q200 Rev-C.  
2. When ceramic capacitors are used at the connection to a battery or power supply (e.g. clamp  
15 or 30 in an automobile) or for safety-relevant applications, two single ceramic capacitors  
should be connected in series. Alternatively a ceramic capacitor with integrated series circuits  
should be used in order to reduce the possibility of a short circuit caused by a fracture. The  
MLSC from EPCOS contains such a series circuit in a single component.  
3. The use of multilayer varistors (MLVs) is recommended for ESD protection (see chapter  
“Effects on mechanical, thermal and electrical stress”, section 1.4).  
4. Additional stress factors such as continuous operating voltage or application-specific derating  
must be taken into account in the selection of components (refer to chapter “Reliability”).  
Recommendations for the circuit board design  
1. Components with an optimized geometrical design are preferable where permitted by the  
application.  
2. Use at least FR4 circuit board material.  
3. Geometrically optimized circuit boards are preferable, especially those that cannot be  
deformed.  
4. Ceramic capacitors should be placed with a sufficient minimum distance from the edge of a  
circuit board. High bending forces may be exerted there when boards are separated and  
during further processing of a board (e.g. when incorporating it in a housing).  
5. Ceramic capacitors should always be placed parallel to the possible bending axis of a circuit  
board.  
6. Screw connections should not be used to fix a board or connect several boards. Components  
should not be placed near screw holes. If screw connections are unavoidable, they should be  
cushioned, for instance using rubber pads.  
Please read Cautions and warnings and  
Important notes at the end of this document.  
Page 15 of 19  
Multilayer ceramic capacitors  
HQF  
Recommendations for processing  
1. Ensure correct positioning of a ceramic capacitor on the solder pad.  
2. Be careful when using casting, injection-molded and molding compounds and cleaning  
agents. They can damage a capacitor.  
3. Support a circuit board and reduce placement forces.  
4. Do not straighten a board (manually) if it is distorted by soldering.  
5. Separate boards with a peripheral saw, or preferably with a milling head (no dicing or  
breaking).  
6. Be careful when subsequently placing heavy or leaded components (e.g. transformers or  
snap-in components) because of the danger of bending and fracture.  
7. When testing, transporting, packing or inserting a board, avoid any deformation of it so that  
components are not damaged.  
8. Avoid excessive force when plugging a connector into a device soldered onto a board.  
9. Only mount ceramic capacitors using the soldering process (reflow or wave) that is  
permissible for them (see chapter “Soldering directions”).  
10. When soldering, select the softest solder profile possible (heating time, peak temperature,  
cooling time) to avoid thermal stress and damage.  
11. Ensure the correct solder meniscus height and solder quantity.  
12. Ensure correct dosing of the cement.  
13. Ceramic capacitors with external silver-palladium terminations are intended for conductive  
adhesion - they are not suited for lead-free soldering processes.  
This listing does not claim to be complete, but merely reflects the experience of EPCOS AG.

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 re-  
quirements 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 incum-  
bent on the customer to check and decide whether an EPCOS product with the properties de-  
scribed 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.
