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
2. At the connection to the battery or power supply (e.g. clamp 15 or 30 in the automobile) and at
3. Ceramic capacitors with the temperature characteristics Z5U and Y5V do not satisfy the require-
4. For ESD protection, preference should be given to the use of multilayer varistors (MLV) (see the
5. An application-specific derating or continuous operating voltage must be considered in order to
The following should be considered in circuit board design
1. If technically feasible in the application, preference should be given to components having an
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
5. Ceramic capacitors should always be placed parallel to the possible bending axis of the circuit
6. No screw connections should be used to fix the board or to connect several boards. Compo-
