General Specification
General introduction:
Ceramic capacitors (or condenser) are widely used in electronic circuitry for coupling, de-coupling and in filters.
These different functions require specific capacitor properties. Ceramic capacitors can be divided into two classes,
Class 1
In these capacitors dielectric materials are used which have a very high specific resistance, very good Q and linear
temperature dependence.
They are used in such applications as oscillators and filters where low losses, capacitance drift compensation and
high stability are required.
Class 2
These capacitors have higher losses and have non-linear characteristics. They are used for coupling and
de-coupling.
Construction:
The capacitance of a ceramic capacitor depends on the area of the electrodes (A), the thickness of the ceramic
dielectric (t) and the dielectric constant of the ceramic material (ε
r
) ; and on the number of dielectric layers (n) with
multi-layer ceramic capacitors :

The standard capacitance unit is the “Farad”. A capacitor has capacitance of one farad is when one coulomb charges
two parallel conductive plate to one volt potential.
The rated voltage is dependent on the dielectric strength, which is mainly governed by the thickness of the dielectric
layer and the ceramic structure. For this reason a reduction of the layer thickness is limited. Figure 1 shows the
construction of a multi-layer capacitor.
The electrodes are normally mixed palladium with silver since the electrodes are applied before the ceramic is fired
at a temperature where silver would oxidize.
Manufacturing of ceramic capacitors
The raw materials are finely milled and carefully mixed. Thereafter the powders are calcined at temperatures
between 1100℃ and 1300℃ to achieve the required chemical composition.
Then, the resultant mass is reground and dopes and/or sintering means are added.
The finely ground material is mixed with a solvent and binding matter. Casting or rolling obtains thin sheets. For
multi-layer capacitors electrode material is printed on the sheets and after stacking and pressing of the sheets
co-fired with the ceramic compact at temperatures between 1000℃ and 1400℃.
The totally enclosed electrodes of a multi-layer capacitor guarantee good life test behavior as well.

Operating Voltage
The operating voltage for the capacitors must always be lower than its rated voltage. If an AC voltage is applied, the
peak voltage should be lower than the rated voltage of the capacitor. And if both AC and a pulse voltage may be
presented, then the sum of the peak should also be lower than the rated voltage of the capacitor chosen.
