        The temperature coefficient of a film capacitor means that the capacitance of the capacitor changes with temperature. When designing a precision capacitor timing circuit and an oscillating circuit whose frequency is determined by the capacitor, the influence of temperature on the capacity of the film capacitor should be fully considered. Otherwise, the timing of the designed film capacitor timing circuit will be inaccurate; the oscillation frequency of the oscillation circuit will be Varies with changes in temperature.


          All in all, when using a capacitor, the effect of temperature on the capacitance should be fully considered, and the capacitor should be made to work at around 20°C to avoid the effect of temperature on many parameters of the capacitor.
