Definitions of Ultra-Stable and Stable
Multilayer Ceramic Capacitors are generally divided into classes
which are defined by the capacitance temperature characteristics
over specified temperature ranges.
These are designated by alpha numeric codes.
Code definitions are summarised below and are also available in the
relevant national and international specifications.

Capacitors within this class have a dielectric constant range from 10
to 100. They are used in applications which require ultra stable
dielectric characteristics with negligible dependence of capacitance
and dissipation factor with time, voltage and frequency. They
exhibit the following characteristics:-
a) Time does not significantly affect capacitance and dissipation
factor (Tan
δ)
– no ageing.
b) Capacitance and dissipation factor are not affected by voltage.
c) Linear temperature coefficient.

Capacitors of this type have a dielectric constant range of 1000-
4000, and also have a non-linear temperature characteristic which
exhibits a dielectric constant variation of less than ±15% (2R1)
from its room temperature value, over the specified temperature
range. Generally used for by-passing (decoupling), coupling,
filtering, frequency discrimination, DC blocking and voltage transient
suppression with greater volumetric efficiency than Class l units,
whilst maintaining stability within defined limits.
