1.7 Capacitance Aging
1.8 Piezoelectricity
Under Ordinary Temperature
(1) If capacitance change caused by the applied voltage
(2) DC voltage characteristics demonstrate that even
The ceramic dielectrics of the Capacitors (Class 2) have
capacitance aging. Accordingly, when the Capacitors
are used for circuits which require a narrow allowable
capacitance range, such as time constant circuits, pay
special attention to capacitance aging before use.
Dielectrics used for the Capacitors (Class 2) may
cause the following Piezoelectricity (or Electrostriction).
(1) If the signal of a specifi c frequency is applied to

In addition, changing the materials of the Capacitors
As a measure to prevent this phenomenon, changing
is within the allowable range, or if its application allows
unlimited capacitance change.
if the applied voltage is under the rated voltage,
the capacitance change rate increases with higher
voltage (Capacitance down). Accordingly, when the
Capacitors are used for circuits with a narrow allowable
capacitance range such as time constant circuits, we
recommend applying a lower voltage after taking
capacitance aging and the above into account.
the Capacitors, electric and acoustic noise may be
generated by resonating the characteristic frequen-
cy, which is determined by the dimensions of the
Capacitor.
As a measure to prevent this phenomenon, changing
the size of the Capacitor is effective in changing its
resonance frequency.

piezoelectricity, or to use Class 1 dielectrics which
have no (or less) piezoelectricity.

indicate a problem with product performance
and reliability, however, check if this undesirable
phenomenon generates noise in your application.
To prevent this phenomenon, changing the Capacitor’s
characteristics, such as size and shape, as
shown in (1) & (2) above can be effective.

When the Capacitors are mounted and soldered on
an “Alumina Substrate”, the substrate infl uences the
Capacitors’ reliability against “Temperature Cycles”
and “Heat shock” due to the difference in the thermal
expansion coeffi cient between them. Confi rm that the
actual board used does not deteriorate the characteristics
of the Capacitors.

of the Capacitors may be effective in getting the
resonance under control with other equipment such as
printed circuit boards. Attaching the Capacitors to
the printed circuit board by an adhesive may also
be effective.
Use the proper amount of solder in order to prevent
cracking. Using too much solder places excessive
stress on the Capacitors.
