6 FAQs about [Temperature resistance range of explosion-proof capacitors]

How to determine the temperature rise above ambient of a capacitor?

If the ESR and current are known, the power dissipation and thus, the heat generated in the capacitor can be calculated. From this, plus the thermal resistance of the ca-pacitor and its external connections to a heat sink, it be-comes possible to determine the temperature rise above ambient of the capacitor.

What is the maximum temperature a capacitor can be soldered to?

Since the maximum temperature of the solder normally used on the terminations of the capacitor is 190° C; 125° C was chosen as the maximum for one se-ries of capacitors.* This ensures the the epoxy or solder. This temperature current, if the capacitor ESR is known.

What is the maximum voltage rating of a capacitor?

the capacitor is 190° C; 125° C was chosen as the maximum for one se-ries of capacitors.* This ensures the the epoxy or solder. This temperature current, if the capacitor ESR is known. The criterion for the maximum voltage rating depends upon the voltage breakdown characteristics of the ca-pacitor.

How do you determine the allowable power dissipation of a capacitor?

As previously stated, the allow-able power dissipation can be determined by the knowledge of the thermal resistance Θcap, the equivalent series resistance ESR of the capacitor, the maximum allowable internal temperature and the maximum temperature that solder or epoxy on the ter-mination can tolerate without destruction.

What happens if a capacitor is stored above room temperature?

When capacitors have been stored above room temperature, the anode foil may react with the electrolyte causing increased leakage current values. Application of normal voltages to these capacitors may result in higher leakage current values, but in most cases, they will return to normal levels in short time.

What temperature should a capacitor be dried at?

However it is advisable to dry immediately with hot air, which is best achieved at 85°C for few minutes. After having a capacitor exposed to high temperatures such as direct sunlight or heating elements, the capacitor life may be adversely affected.
