How temperature affects Capacitor (Ⅱ)

Insulation Resistance of Capacitance affected by temperature.

In general, the insulation resistance of the capacitance decreases with the increase of temperature, and the decrease of the insulation resistance will lead to the increase of leakage current of the capacitance, so the working of the capacitance is the most stable at normal temperature.

Temperature affects the capacity of capacitors.

The capacitance varies with temperature. When designing precise capacitive timing circuit and oscillating circuit with frequency determined by capacitance, the effect of temperature on capacitance should be fully taken into account, otherwise. The designed capacitor timing circuit will not be accurate; The oscillation frequency of the oscillating circuit changes with the change of temperature.

In a word, when using capacitors, the effect of temperature on capacitors should be fully taken into account, and the capacitors should be operated at about 20 ℃ to avoid the influence of temperature on many parameters of capacitors.
