6 FAQs about [The temperature characteristics of film capacitors are]
What is the climatic category of a film capacitor?
The lowest frequency at which the impedance of the capacitor is a minimum when applying a sinusoidal voltage. The ambient free air temperature is the temperature of the air surrounding the component. The climatic category code (e.g. 50 / 100 / 56) indicates to which climatic category a film capacitor type belongs.
Why are film capacitors better than other types of capacitors?
In addition, film capacitors have a smaller loss of electricity when charging/discharging as compared to other types of capacitors. In particular, film capacitors made with PP dielectric material not only operate with very small loss, but also maintain its small loss even with temperature changes. Some capacitors pose polarity.
How does temperature affect the capacitance of a capacitor?
The capacitance value of a capacitor varies with the changes in temperature which is surrounded the capacitor. Because the changes in temperature, causes to change in the properties of the dielectric. Working Temperature is the temperature of a capacitor which operates with nominal voltage ratings.
