11 10/06

Multilayer ceramic capacitors

Cautions and warnings

Notes on the selection of ceramic capacitors

In the selection of ceramic capacitors, the following criteria must be considered:

1. Depending on the application, ceramic capacitors used to meet high quality requirements should

at least satisfy the specifications to AEC-Q200. They must meet quality requirements going

beyond this level in terms of ruggedness (e.g. mechanical, thermal or electrical) in the case of

critical circuit configurations and applications (e.g. in safety-relevant applications such as ABS

and airbag equipment or durable industrial goods).

2. At the connection to the battery or power supply (e.g. clamp 15 or 30 in the automobile) and at

positions with stranding potential, to reduce the probability of short circuits following a fracture,

two ceramic capacitors must be connected in series and/or a ceramic capacitor with integrated

series circuit should be used. The MLSC from EPCOS contains such a series circuit in a single

component.

3. Ceramic capacitors with the temperature characteristics Z5U and Y5V do not satisfy the require-

ments to AEC-Q200 and are mechanically and electrically less rugged than C0G or X7R/X8R

ceramic capacitors. In applications that must satisfy high quality requirements, therefore, these

capacitors should not be used as discrete components (see the chapter “Effects on mechanical,

thermal and electrical stress”, point 1.4).

4. For ESD protection, preference should be given to the use of multilayer varistors (MLV) (see the

chapter “Effects on mechanical, thermal and electrical stress”, point 1.4).

5. An application-specific derating or continuous operating voltage must be considered in order to

cushion (unexpected) additional stresses (see the chapter “Reliability”).

The following should be considered in circuit board design

1. If technically feasible in the application, preference should be given to components having an

optimal geometrical design.

2. At least FR4 circuit board material should be used.

3. Geometrically optimal circuit boards should be used, ideally those that cannot be deformed.

4. Ceramic capacitors must always be placed a sufficient minimum distance from the edge of the

circuit board. High bending forces may be exerted there when the panels are separated and dur-

ing further processing of the board (such as when incorporating it into a housing).

5. Ceramic capacitors should always be placed parallel to the possible bending axis of the circuit

board.

6. No screw connections should be used to fix the board or to connect several boards. Compo-

nents should not be placed near screw holes. If screw connections are unavoidable, they must

be cushioned (for instance by rubber pads).

12 10/06

Multilayer ceramic capacitors

Cautions and warnings

The following should be considered in the placement process

1. Ensure correct positioning of the ceramic capacitor on the solder pad.

2. Caution when using casting, injection-molded and molding compounds and cleaning agents,

as these may damage the capacitor.

3. Support the circuit board and reduce the placement forces.

4. A board should not be straightened (manually) if it has been distorted by soldering.

5. Separate panels with a peripheral saw, or better with a milling head (no dicing or breaking).

6. Caution in the subsequent placement of heavy or leaded components (e.g. transformers or

snap-in components): danger of bending and fracture.

7. When testing, transporting, packing or incorporating the board, avoid any deformation of the

board not to damage the components.

8. Avoid the use of excessive force when plugging a connector into a device soldered onto the

board.

9. Ceramic capacitors must be soldered only by the mode (reflow or wave soldering) permissible

for them (see the chapter “Soldering directions”).

10. When soldering the most gentle solder profile feasible should be selected (heating time, peak

temperature, cooling time) in order to avoid thermal stresses and damage.

11. Ensure the correct solder meniscus height and solder quantity.

12. Ensure correct dosing of the cement quantity.

13. Ceramic capacitors with an AgPd external termination are not suited for the lead-free solder

process: they were developed only for conductive adhesion technology.

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

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 passive 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 a passive 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 a passive 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.

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, EPCOS-JONES, Baoke, CeraDiode, CSSP, MLSC, PhaseCap,

PhaseMod, SIFERRIT, SIFI, SIKOREL, SilverCap, SIMID, SIOV, SIP5D, SIP5K, UltraCap,
