CAPACITANCE CHANGE VS. TEMPERATURE (Typical)

STORAGE

The capacitors must not be stored in a corrosive atmosphere, where sulphide or chloride gas, acid, alkali or salt are present.

Exposure of the components to moisture, should be avoided. The solderability of the leads is not affected by storage of up to

24 months (temperature +10 °C to +40 °C, relative humidity up to 60 % RH). Class 2 ceramic dielectric capacitors are also

SOLDERING

SOLDERING RECOMMENDATIONS

Ceramic capacitors are very sensitive to rapid changes in temperature (thermal shock) therefore the solder heat resistance

specification (see table above) should not be exceeded. Exposing the capacitor to excessive heating may result in thermal

shocks that can crack the ceramic body. Similarly, excessive heating can cause the internal solder junction to melt.
