CAPACITANCE “AGING” OF CERAMIC CAPACITORS
Following the final heat treatment, all class 2 ceramic capacitors reduce their capacitance value. According to logarithmic law,
this is due to their special crystalline construction. This change is called “aging”. If the capacitors are heat treated (for example
when soldering), the capacitance increases again to a higher value deaging, and the aging process begins again.
Note
• The level of this deaging is dependent on the temperature and the duration of the heat; an almost complete deaging is achieved at 150 °C
REFERENCE MEASUREMENT
Due to aging, it is necessary to quote an age for reference measurements which can be related to the capacitance with fixed
tolerance. According to EN 130700, this time period is 1000 h.
In order to avoid the influence of aging, it is important to deage the capacitors before stress-testing. The following procedure is
adopted (see also EN 130700):

in one hour. These conditions also form the basis for reference measurements when testing. The capacitance change per time decade
(aging constant) differs for the various types of ceramic, but typical values can be taken from the equations below.
k =
C 11 x log 10 (t2/t1)
100 x (C 11 - C 12 )
C12 = C11 x (1 - k/100 x log10 [t2/t1])
