The difference between "operating temperature range" and "temperature range" in the specifications of ceramic capacitors is shown below.
|Operating temperature range
|The temperature range in which the target capacitor can be used continuously according to its design (the operating temperature is measured on the surface of the product itself).
|The temperature range in which the target capacitor satisfies the capacitance change ratio or temperature coefficient as the temperature characteristics of the target capacitor.
for information about how the capacitance changes when the capacitor is outside its temperature range but inside its operating temperature range.
