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
