HEAT CONDUCTIVITY (G) AS A FUNCTION OF ORIGINAL 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 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 (ΔT) can be measured (see section “Measuring the Component Temperature” for more details)
or calculated by ΔT = P/G:
•
• P = Power dissipation of the component (mW)
• G = Heat conductivity of the component (mW/°C)
