Recommended derating conditions on voltage and temperature
These Part Numbers are designed for use in the circuits w here
continuous applied voltage to the capacitor is derated than rated
voltage, and guarantee Durability Test w ith 125% × rated voltage
as testing voltage at the maximumoperating temperature.
The voltage and temperature derating conditions on the left are
recommended for use to ensure the same reliability level as
normal specification.
