engineers.
for a sine wave voltage.
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 B
characteristic capacitors. However, if the self-heating
temperature is 20 C under a high-frequency voltage
whose peak-to-peak value equals the capacitor's rated
voltage, the capacitor's power consumption may exceed
its allowable electric power.
Therefore, when using the DEA/DEC (SL Char.) /DEH
/DES series in a high-frequency and high-voltage circuit
with a frequency of 1kHz or higher, make sure that the
Vp-p values including the DC bias, do not exceed the
applied voltage value specified in Table 1. Also make
sure that the self-heating temperature (the difference
between the capacitor's surface temperature and the
capacitor's ambient temperature) at an ambient
temperature of 25 C does not exceed the value specified
in Table 1.
As shown in Fig. 2, the self-heating temperature
depends on the ambient temperature. Therefore, if you
are not able to set the ambient temperature to
approximately 25 C, please contact our sales
representatives or product engineers.

We are offering free software, The Capacitor Selection
Tool: by Voltage Form, which will assist you in selecting a
suitable capacitor.
The software can be downloaded from Murata's Web site
(http://www.murata.com/products/design_support/mmcsv/
index.html).
By inputting capacitance values and applied voltage
waveform of the specific capacitor series, this software
will calculate the capacitor's power consumption and list
suitable capacitors.
When the result of this software is different from the
measurement result of the self-heating temperature on
your side, please contact our sales representatives or
product engineers.
