!Caution (Rating)
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 that 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.
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 current, pulse current or similar current, it may
have self-generated heat due to dielectric loss. Applied
voltage load should be such that self-generated heat is
within 20 C under the condition where the capacitor is
subjected to an atmospheric temperature of 25 C. When
measuring, use a thermocouple of small thermal
capacity-K of ø0.1mm under conditions where the
capacitor is not affected by radiant heat from other
components or wind from surroundings. 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.)
Test equipment for AC withstanding voltage should be
used with the performance of the wave similar to
50/60Hz sine wave.
If the distorted sine wave or overload exceeding the
specified voltage value is applied, a defect may be
caused.
