■ Caution (Rating)
1. Operating Voltage
When DC-rated capacitors are to be used in AC or ripple
current circuits, be sure to maintain the Vp-p value of the
applied voltage or the Vo-p which contains DC bias within
the rated voltage range.
When the voltage is applied to the circuit, starting or
stopping may generate irregular voltage for a transit
period because of resonance or switching. Be sure to use
a capacitor with a rated voltage range that includes these
irregular voltages.
When DC-rated capacitors are to be used in input circuits
from commercial power source (AC filter), be sure to use
Safety Certified Capacitors because various regulations
on withstand voltage or impulse withstand established for
each equipment should be taken into considerations.

2. Operating Temperature, Self-generated Heat, and
Load Reduction at High-frequency Voltage Condition
Keep the surface temperature of a capacitor below the
upper limit of its rated operating temperature range.
Be sure to take into account the heat generated by the
capacitor itself. When the capacitor is used in a high-
frequency voltage, pulse voltage, it may self-generate
heat due to dielectric loss.
(1) In case of X7R char.
Applied voltage should be the load such as self-
generated heat is within 20°C on the condition of
atmosphere temperature 25°C. When measuring, use a
thermocouple of small thermal capacity -K of ø0.1mm
in conditions where the capacitor is not affected by
radiant heat from other components or surrounding
ambient fluctuations. Excessive heat may lead to
deterioration of the capacitor's characteristics and
reliability. (Never attempt to perform measurement
with the cooling fan running. Otherwise, accurate
measurement cannot be ensured.)
