1. Operating Temperature
1. The operating temperature limit depends on the
capacitor.
1-1. Do not apply temperatures exceeding the upper
operating temperature.
It is necessary to select a capacitor with a suitable
rated temperature which will cover the operating
temperature range.
Also it is necessary to consider the temperature
distribution in equipment and the seasonal
temperature variable factor.
1-2. Consider the self-heating of the capacitor
The surface temperature of the capacitor shall be
the upper operating temperature or less when
including the self-heating factors.
2. Atmosphere Surroundings (gaseous and liquid)
1. Restriction on the operating environment of capacitors.
1-1. The capacitor, when used in the above, unsuitable,
operating environments may deteriorate due to
the corrosion of the terminations and the
penetration of moisture into the capacitor.
1-2. The same phenomenon as the above may occur
when the electrodes or terminals of the capacitor
are subject to moisture condensation.
1-3. The deterioration of characteristics and insulation
resistance due to the oxidization or corrosion of
terminal electrodes may result in breakdown when
the capacitor is exposed to corrosive or volatile
gases or solvents for long periods of time.
3. Piezo-electric Phenomenon
1. When using high dielectric constant type capacitors in
AC or pulse circuits, the capacitor itself vibrates at
specific frequencies and noise may be generated.
Moreover, when the mechanical vibration or shock is
added to capacitor, noise may occur.
