1-2. The load should be contained so that the self-heating
of the capacitor body remains below 20°C, when
measuring at an ambient temperature of 25°C. In
addition, use a K thermocouple of ø0.1mm with less
heat capacity when measuring, and measure in a
condition where there is no eect from the radiant
heat of other components or air flow caused by
convection. Excessive generation of heat may cause
deterioration of the characteristics and reliability of the
capacitor. (Absolutely do not perform measurements
while the cooling fan is operating, as an accurate
measurement may not be performed.)
<Applicable to Temperature Characteristics U2J (7U),
C0G (5C) beyond Rated Voltage of 200VDC>
1-3. Since the self-heating is low in the low loss series, the
allowable power becomes extremely high compared to
the common X7R (R7) characteristics.
However, when a load with self-heating of 20°C is
applied at the rated voltage, the allowable power may
be exceeded. When the capacitor is used in a
high-frequency voltage circuit of 1kHz or more, the
frequency of the applied voltage should be less than
500kHz sine wave (less than 100kHz for a product
with rated voltage of DC3.15kV), to limit the voltage
load so that the load remains within the derating
shown in the following figure. In the case of non-sine
wave, high-frequency components exceeding the
fundamental frequency may be included. In such a case,
please contact Murata. The excessive generation of
heat may cause deterioration of the characteristics
and reliability of the capacitor.
(Absolutely do not perform measurements while the
cooling fan is operating, as an accurate measurement
may not be performed.)
The surface temperature of the capacitor: 125°C or less
(including self-heating)
