6 FAQs about [The normal operating temperature of the capacitor]
What is a normal working temperature for a capacitor?
The normal working range for most capacitors is -30 o C to +125 o C with nominal voltage ratings given for a Working Temperature of no more than +70 o C especially for the plastic capacitor types.
What are the temperature characteristics of ceramic capacitors?
The temperature characteristics of ceramic capacitors are those in which the capacitance changes depending on the operating temperature, and the change is expressed as a temperature coefficient or a capacitance change rate. There are two main types of ceramic capacitors, and the temperature characteristics differ depending on the type. 1.
Why does temperature change in a 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. The general working temperatures range for most capacitors is -30°C to +125°C. In plastic type capacitors this temperature value is not more than +700C.
What is the temperature coefficient of a capacitor?
The Temperature Coefficient of a capacitor is the maximum change in its capacitance over a specified temperature range. The temperature coefficient of a capacitor is generally expressed linearly as parts per million per degree centigrade (PPM/ o C), or as a percent change over a particular range of temperatures.
What happens if a capacitor is too hot?
If the surrounding temperature of the capacitor is more than the rated operating temperature, the capacitance of the capacitor can change significantly so it can impact the overall operation of the circuit. The normal working temperature for most practical capacitors is ranging between -30 °C and +125 °C.
What factors should be considered when choosing a capacitor?
Also it is recommended to consider the temperature distribution in equipment and seasonal temperature variable factor. When the capacitor is used at a temperature above the upper category temperature, insulation resistance of the capacitor may deteriorate and cause rapid current increase and a short circuit.
