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 air ambient temperature.

The power dissipation can be calculated according type detail specification “HQN-384-01/101: Technical Information Film

Capacitors” with the typical t_gdof the curves.

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:

Thermocouple

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

To select the capacitor for a certain application, the following conditions must be checked:

1. The peak voltage (U_p) shall not be greater than the rated DC voltage (U_RDC).

2. The peak-to-peak voltage (U_p-p) shall not be greater than the maximum (U_p-p) to avoid the ionization inception level.

3. The maximum component surface temperature rise must be lower than the limits.

4. The maximum application temperature must be lower than 105 °C.

5. There is no limit for the voltage pulse slope in the application.
