HEAT CONDUCTIVITY AND HOT SPOT TEMPERATURE
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 component temperature rise (ΔT) can be measured or calculated by ΔT = P/G:
•
• P = Power dissipation of the component (mW)
• G = Heat conductivity of the component (mW/°C)
MEASURING THE COMPONENT TEMPERATURE
The temperature is measured in unloaded (T
The temperature rise is given by ΔT = T
To avoid thermal radiation or convection, the capacitor must be tested in a closed area from air circulation.
