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 tgd of 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

CBA758

The temperature is measured in unloaded (Tamb) and maximum loaded condition (TC).

The temperature rise is given by T = TC - Tamb.

To avoid radiation or convection, the capacitor should be tested in a wind-free box.
