POWER DISSIPATION AND MAXIMUM COMPONENT TEMPERATURE RISE
The power dissipation must be limited in order not to exceed the maximum allowed component temperature rise as a function
of the free ambient temperature.
The power dissipation can be calculated according type detail specification “HQN-384-01/101: Technical Information Film
Capacitors”.
The component temperature rise (T) can be measured (see section “Measuring the Component Temperature” for more details)
or calculated by T = P/G:
• T = component temperature rise (°C)
• P = power dissipation of the component (mW)
• G = heat conductivity of the component (mW/°C)
MEASURING THE COMPONENT TEMPERATURE
A thermocouple must be attached to the capacitor body as in:
The temperature is measured in unloaded (T
amb
) and maximum loaded condition (T
C
).
The temperature rise is given by T = T
C
- T
amb
.
To avoid radiation or convection, the capacitor should be tested in a wind-free box.
APPLICATION NOTE AND LIMITING CONDITIONS
These capacitors are not suitable for mains applications as across-the-line capacitors without additional protection, as
described hereunder. These mains applications are strictly regulated in safety standards and therefore electromagnetic
interference suppression capacitors conforming the standards must be used.
To select the capacitor for a certain application, the following conditions must be checked:
1. For capacitors connected in parallel, normally the proof voltage and possibly the rated voltage must be reduced. For
information depending of the capacitance value and the number of parallel connections contact: dc-film@vishay.com
2. The peak voltage (U
P
) shall not be greater than the rated DC voltage (U
RDC
)
3. The peak-to-peak voltage (U
P-P
) shall not be greater than 22 x U
RAC
to avoid the ionization inception level
4. The voltage pulse slope (dU/dt) shall not exceed the rated voltage pulse slope in an RC-circuit at rated voltage and without
ringing. If the pulse voltage is lower than the rated DC voltage, the rated voltage pulse slope may be multiplied by U
RDC
and
divided by the applied voltage.
For all other pulses following equation must be fulfilled:
T is the pulse duration.
The rated voltage pulse slope is valid for ambient temperatures up to 85 °C. For higher temperatures a derating factor of
3 % per K shall be applied.
