Low Losses Ultra high voltage capacitors DC 20 KVDC 100pf ceramic capacitor

 

Application classes, definitions

 

The different ceramic materials used for ceramic capacitors, paraelectric or ferroelectric ceramics, influences the electrical characteristics of the capacitors. Using mixtures of paraelectric substances based on titanium dioxide results in very stable and linear behavior of the capacitance value within a specified temperature range and low losses at high frequencies. But these mixtures have a relatively low permittivity so that the capacitance values of these capacitors are relatively small. Higher capacitance values for ceramic capacitors can be attained by using mixtures of ferroelectric materials like barium titanate together with specific oxides. These dielectric materials have much higher permittivities, but at the same time their capacitance value are more or less nonlinear over the temperature range, and losses at high frequencies are much higher. These different electrical characteristics of ceramic capacitors requires to group them into “application classes”. The definition of the application classes comes from the standardization. As of 2013, two sets of standards were in use, one from International Electrotechnical Commission (IEC) and the other from the now-defunct Electronic Industries Alliance (EIA).

 

Unfortunately the definitions of the application classes given in the two standards are different. The following table shows the different definitions of the application classes for ceramic capacitors:

 

Different definitions of application classes for ceramic capacitors

 

Definition regarding to IEC/EN 60384-1 and IEC/EN 60384-8/9/21/22 Definition regarding to EIA RS-198
Class 1 ceramic capacitors offer high stability and low losses for resonant circuit applications.
Class I (or written class 1) ceramic capacitors offer high stability and low losses for resonant circuit application
Class 2 ceramic capacitors offer high volumetric efficiency for smoothing, by-pass, coupling and decoupling applications Class II (or written class 2) ceramic capacitors offer high volumetric efficiency with change of capacitance lower than -15% to +15% and a temperature range greater than -55 °C to +125 °C,
for smoothing, by-pass, coupling and decoupling applications
Class 3 ceramic capacitors are barrier layer capacitors which are not standardized anymore Class III (or written class 3) ceramic capacitors offer higher volumetric efficiency than EIA class II and typical change of capacitance by -22% to +56% over a lower temperature range of 10 °C to 55 °C.
They can be substituted with EIA class 2- Y5U/Y5V or Z5U/Z5V capacitors-
  Class IV (or written class 4) ceramic capacitors are barrier layer capacitors which are not standardized anymore
