HEAT CONDUCTIVITY (G) AS A FUNCTION OF PITCH AND CAPACITOR BODY THICKNESS IN mW/°C
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 (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:
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.
