When capacitor companies develop products, they choose materials with characteristics that will enable the capacitors to operate within the specified variation (3rd character) over the specified temperature range (1st and 2nd character). The X7R capacitors that I was using should not vary more than ±15% over a temperature range of −55°C to +125°C. OK, so either I had a bad
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
operated at room temperature can have life expectancies of several years compared to operating the capacitors at their maximum rated temperature. L 1= Load life rating of the super capacitor (typically 1000 hours at rated temperature). L 2 = expected life at operating condition. CDE Supercapacitor Technical Guide – Page 9 Tm= Maximum temperature rating of the
New axial-leaded, hermetically sealed wet tantalum electrolytic capacitors are also capable of 230°C maximum operating temperatures. They are currently available in the standard T4 case size, measuring 26.97-mm long and 10.31 mm in diameter with an insulating sleeve. This series represents the largest standard case size for axial-leaded wet
Looking at these charts you see, an "NP0" capacitor with EIA code "C0G" will have 0 drift, with a tolerance of ±30 ppm/K, while an "N1500" with the code "P3K" will have −1500 ppm/K drift, with a maximum tolerance of
No. +85°C is the maximum temperature you can use it at. Anything lower will do fine, higher temperatures will damage the component. But regarding its lifetime, it is never
You can apply maximum 10.7V to the capacitor for the entire operating temperature range to 125°C (voltage derating 20% is covered by the 33% temperature derating). Thus 16V capacitor is NOT suitable for 125°C device due to the high temperature. Need higher rated 20V tantalum polymer capacitor.
Any operating temperature should not exceed the upper category temperature. It is necessary to select a capacitor whose rated temperature is higher than the operating temperature. Also it is
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 temperature, and thus it would be invalid to estimate the lifetime at temperatures above it with the same formula, as the component would be used outside the rated operating tempetature range so none of the
*2 Maximum operating temperature: By design, maximum ambient temperature including self-heating 20°C MAX that allows continuous use of capacitors. The EIA standard specifies various capacitance temperature factors ranging from 0ppm/°C to −750ppm/°C.
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, coupling and decoupling applications
Heating to 200°C for 10 minutes for a second time probably won''t ruin your capacitors, but it may reduce their life. The most important, however, is the peak temperature phase, where the temperature goes for a short time (about half a minute) to about 250°C, depending on package volume. This is the phase where the actual soldering takes place.
θHS (°C) Hot spot temperature Highest temperature obtained inside the case of the capacitor in thermal equilibrium. θ (°C) Operating temperature Temperature of the hottest point on the case of the capacitor in thermal equilibrium. θmin (°C) Minimum operating temperature Lowest temperature of the dielectric at which the capacitor may be
maximum operating tempera-ture. Dielectric Strength is the maximum peak voltage that the capacitor is rated to with-stand at room temperature. Test by applying the specified multiple of rated voltage for one minute through a current-limiting resistance of 100 per volt. As an illustration, to test a Type DPM capacitor rated 250 Vdc and 175% dielectric strength, apply 438 Vdc
In general, tantalum and ceramic capacitors are the most frequently used for applications operating at temperatures above 175 oC. Most MLCC high temperature offerings are designed
to accurately predict capacitor operating temperature and expected life from operating conditions. Operating conditions permitted as inputs include applied voltage, ambient air temperature, air speed, thermal resistance of any heatsink attached, and capacitor characteristics like capacitance, ESR and case size.

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. Table 1. TDK
No. +85°C is the maximum temperature you can use it at. Anything lower will do fine, higher temperatures will damage the component. But regarding its lifetime, it is never wise to use components near their maximum ratings.

The temperature coefficient (TC) of a capacitor describes the maximum change in the capacitance value with a specified temperature range. Generally the capacitance value which is printed on the body of a capacitor is measured with the reference of temperature 250C and also the TC of a capacitor which is mentioned in the datasheet must be

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. The higher cold resistivity increases the capacitor''s ESR 10 to 100 fold and reduces the available capacitance.
*2 Maximum operating temperature: By design, maximum ambient temperature including self-heating 20°C MAX that allows continuous use of capacitors. The EIA standard specifies various capacitance temperature factors ranging from 0ppm/°C to −750ppm/°C. Figure 1 below shows typical temperature characteristics.
Heating to 200°C for 10 minutes for a second time probably won't ruin your capacitors, but it may reduce their life. The most important, however, is the peak temperature phase, where the temperature goes for a short time (about half a minute) to about 250°C, depending on package volume.
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.
Changes in temperature around the capacitor affect the value of the capacitance because of changes in the dielectric properties. If the air or surrounding temperature becomes to hot or to cold the capacitance value of the capacitor may change so much as to affect the correct operation of the circuit.
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.
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.
