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 (ΔT) can be measured (see section “Measuring the component temperature” for more details)
or calculated by ΔT = P/G:
MEASURING THE COMPONENT TEMPERATURE
A thermocouple must be attached to the capacitor body as in:
The temperature is measured in unloaded (T
The temperature rise is given by ΔT = T
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. The peak voltage (U
2. The peak-to-peak voltage (U
3. The voltage peak slope (dU/dt) shall not exceed the rated voltage pulse slope in an RC-circuit at rated voltage and without
4. The maximum component surface temperature rise must be lower than the limits (see figure max. allowed component

ringing. If the pulse voltage is lower than the rated DC voltage, the rated voltage pulse slope may be multiplied by U
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.
