(2) In case of C0G, U2J char.
Due to the low self-heating characteristics of
low-dissipation capacitors, the allowable electric power of
these capacitors is generally much higher than that of
X7R characteristic capacitors.
When a high frequency voltage that causes 20°C self-
heating to the capacitor is applied, it will exceed the
capacitor's allowable electric power.
The frequency of the applied sine wave voltage should be
less than 500kHz (less than 100kHz in the case of rated
voltage: DC3.15kV). The applied voltage should be less
than the value shown in figure below.
In the case of non-sine wave that includes a harmonic
frequency, please contact our sales representatives or
product engineers. 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.)
<C0G char., Rated Voltage: DC3.15kV>
The capacitors less than 22pF can be applied maximum
4.0kV peak to peak at 100kHz or less only for the ballast
or the resonance usage in the LCD backlight inverter
circuit.
<Capacitor Selection Tool>
We are also offering free software/the capacitor selection
tool: "Murata Medium Voltage Capacitors Selection Tool
by Voltage Form," which will assist you in selecting a
suitable capacitor.
The software can be downloaded from Murata's Website.
(http://www.murata.com/designlib/mmcsv/index.html).
By inputting capacitance values and the applied voltage
waveform of the specific capacitor series, this software
will calculate the capacitor's power consumption and list
suitable capacitors (non-sine wave is also available).
