Discrete capacitors deviate from the ideal capacitor. An ideal capacitor only stores and releases electrical energy, with no dissipation. Capacitor components have losses and parasitic inductive parts. These imperfections in material and construction can have positive implications such as linear frequency and temperature behavior in class 1 ceramic capacitors. Conversel…

Class 1 ceramic capacitors and film capacitors do not have ferroelectric-related aging. Environmental influences such as higher temperature, high humidity and mechanical stress can, over a longer period, lead to a small irreversible change in the capacitance value sometimes called aging, too.
Class 1 capacitors have low permitivity and hence the efficiency in terms of volume is relatively low. Therefore, the capacitance range of class 1 capacitors is low. The electrical losses of class 1 capacitors are very low and the dissipation factor is 0.15 percent. The value of the capacitance is independent of the applied voltage.
Class 2 . This type of capacitor possesses high permittivity resulting in better volumetric efficiency than class 1 capacitors. It has lower accuracy and stability for smoothing, by-pass, coupling and decoupling applications It exhibits a non-linear temperature coefficient; Class 3

Class I capacitors are primarily made of calcium zirconate, a dielectric material that is very stable across temperature but has much lower relative permittivity than class II, and therefore has much lower overall capacitance. The tolerance of capacitance across a -55C to 125C temperature range is measured in PPM. For example, using the ...
Class 1 capacitors also offer the best performance with respect to dissipation factor. This can be important in many applications. A typical figure may be 0.15%. It is also possible to obtain very high accuracy (~1%) class 1 capacitors rather than the more usual 5% or 10% tolerance versions. The highest accuracy class 1 capacitors are ...
