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:

Thermocouple

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.

APPLICATION NOTE AND LIMITING CONDITIONS

These capacitors are not suitable for mains applications as across-the-line capacitors without additional protection, as

described hereunder. These mains applications are strictly regulated in safety standards and therefore electromagnetic

interference suppression capacitors conforming the standards must be used.

For capacitors connected in parallel, normally the proof voltage and possibly the rated voltage must be reduced. For information

depending of the capacitance value and the number of parallel connections contact: dc-film@vishay.com

To select the capacitor for a certain application, the following conditions must be checked:

1. The peak voltage (U_P) shall not be greater than the rated DC voltage (U_RDC

)

2. The peak-to-peak voltage (U_P-P) shall not be greater than 22 x U_RACto avoid the ionization inception level

3. The voltage peak slope (dU/dt) shall not exceed the rated voltage pulse slope in an RC-circuit at rated voltage and without

ringing. If the pulse voltage is lower than the rated DC voltage, the rated voltage pulse slope may be multiplied by U_RDCand

divided by the applied voltage.

For all other pulses following equation must be fulfilled:

rated

T is the pulse duration.

4. The maximum component surface temperature rise must be lower than the limits (see graph “Max. allowed component

temperature rise”).

5. Since in circuits used at voltages over 280 V peak-to-peak the risk for an intrinsically active flammability after a capacitor

breakdown (short circuit) increases, it is recommended that the power to the component is limited to 100 times the values

mentioned in the table: “Heat Conductivity”

6. When using these capacitors as across-the-line capacitor in the input filter for mains applications or as series connected

with an impedance to the mains the applicant must guarantee that the following conditions are fulfilled in any case (spikes

and surge voltages from the mains included).
