Capacitors (and semiconductors) should have such a soldering cycle specified in the datasheet. The temp spec -40 to +85 refers to continuous use in the end application. The capacitance within this temperature range may vary as specified by the dielectric temperature curve (X5R, NP0 etc) and tolerance (+/-10% etc).

Silicon capacitors also have a wider operating temperature range than general MLCCs, providing stable capacitance even at higher temperatures. Ringing Noise Ringing noise is often discovered during final product evaluation, requiring prompt action before the set is sold, as it can cause significant damage.

tolerances of ±30ppm/oC over the temperature range oof -55 C to +125oC. However, TDK uses both NP0 and C0G to differentiate operating temperature ranges for class 1 capacitors. TDK extends the operating temperature range of NP0 to +150oC. TDK Class 1 Ratings C0G -55 oC to +125 oC ±30ppm/ oC NP0 -55 oC to +150 oC ±30ppm/oC Table 1.
It is not only about ambient temperature, but the actual operating temperature of the capacitor, which includes temperature rise due to internal heating from ripple current and ESR. It is true that capacitors have a certain lifetime guarantee at certain temperature, but in general that rating is already given at the maximum operating
Excessive temperature shortens capacitor lifespan and may lead to dielectric breakdown, causing capacitor damage. Temperature requirements typically range from -40℃ to 40℃ for general capacitors and -45℃ to 50℃ for self-healing capacitors. II. Precautions During Compensation Capacitor Operation. 1.Ensure the ambient temperature does not
Even then, the diminished life expectancy of the capacitors from the higher operating temperatures will still have them outlive the useful life of the router. Mechically the temperature gradient between a 70*F and 100*F ambient room temperature with regards to radiant heat transfer isn''t too drastic

Capacitance loss for high-voltage capacitors can be up to 40%. When operating at the low-temperature limit, the capacitance of aluminum electrolytic capacitors with a low temperature rating of -550C declines by less than 20%.

Other Safety Measures in Operating Theatres. Maintaining the correct temperature and humidity in the operating theatre is essential for both staff and patient safety. But this is just one aspect of a safe and productive operating theatre. In addition to temperature control, the following measures are crucial: Zoning for Infection Control
The normal working range for most capacitors is -30°C to +125°C with nominal voltage ratings given for a Working Temperature of no more than +70°C
This means that my system is limited by ceramic capacitors (rated to +85ºC), which seems intuitively incorrect. Also it should be noted that an X7R or C0G (which generally have higher operating temperature ratings)
An operating room (OR) is a designated area within the hospital specifically equipped to perform surgical procedures. The doctor or nurse will check the patient''s vital signs, including their blood pressure, heart rate, temperature, and oxygen saturation. These baseline readings help evaluate their overall health and suitability for surgery.
The first character indicates the lowest temperature that the capacitor can handle. The letter X (as in X7R, X5R) corresponds to –55°C. The second character indicates the maximum temperature. The theoretical range is
Zero implies zero variation. Below, "Podotresno" in Indonesia shows the difference between a temperature stable and capacitor compared to a cheaper alternative, using a $30 multimeter and a butane lighter.

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. Some capacitors are non linear

A capacitor consists of any two conductors (such as parallel plates) that are separated by an insulator. A capacitor stores charge (electrons). In a DC circuit the capacitor plates are charged by a voltage source (i.e., a battery) and there is only a momentary current flow as the capacitor charges. No further current can then flow unless a

Class II (or written class 2) ceramic capacitors offer high volumetric efficiency with change of capacitance lower than −15% to +15% and a temperature range greater than −55 °C to +125 °C, for smoothing, by-pass,
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.
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.
For long periods of storage keep capacitors at cool room temperatures and in an atmosphere free of halogen gases like chlorine and fluorine that can corrode aluminum. Storage temperature ranges are from –55 ºC to the upper limit of the operating-temperature ranges. Sources: Capacitor Selection Guide - KEMET (.PDF)

The EIA standard specifies various capacitance temperature factors ranging from 0ppm/°C to −750ppm/°C. Figure 1 below shows typical temperature characteristics.
The Operating Temperature Range is the temperature range over which the part will function, when electrified, within the limits given in the specification. It is the range of ambient temperatures for which the capacitor has been designed to operate continuously. Largely the formation voltage sets the high-temperature limit.
Largely the formation voltage sets the high-temperature limit. Higher formation voltages permit higher operating temperatures but reduce the capacitance. The low-temperature limit of an electrolytic capacitor is set largely by the cold resistivity of the electrolyte.
