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 ( ? T) can be measured or calculated by ? T = P/G:
? ? T = Component temperature rise (°C) with a maximum of 15 °C
? P = Power dissipation of the component (mW)
? G = Heat conductivity of the component (mW/°C)
MEASURING THE COMPONENT TEMPERATURE
Thermocouple
The case 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 thermal radiation or convection, the capacitor must be tested in a closed area from air circulation.
APPLICATION NOTE AND LIMITING CONDITIONS
These capacitors are not suitable for mains applications as across-the-line capacitors without additional protection. ?
These mains applications are strictly regulated in safety standards and therefore electromagnetic interference suppression
capacitors conforming the standards must be used.
To select the capacitor for a certain application, the following conditions must be checked:
? The peak voltage (U P+ ) shall not be greater than ? 2 x U RMS
? The peak-to-peak ripple voltage (U PP ) shall not be greater than 0.2 x ? 2 x U RMS
? The voltage pulse slope (dU/dt) shall not exceed the rated pulse slope at the DC voltage rating. ?
If the pulse voltage is lower than the rated DC voltage, the rated voltage pulse slope may be multiplied by U NDC and divided
by the applied voltage. ?
For all other pulses following equation must be fulfilled: ?
T
dU 2 dU
0
T is the pulse duration
? The maximum component surface temperature must be lower than 105 °C and maximum temperature rise between case and
free air ambient shall be lower than 15 °C.
