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 +35 °C, relative humidity up to 60 %). Class 2 ceramic dielectric capacitors are also subject
to aging, see www.vishay.com/doc?22001.

SOLDERING RECOMMENDATIONS
Soldering of the component should be achieved using a Sn60/40 type or a silver-bearing Sn62/36/2Ag type solder. Ceramic
capacitors are very sensitive to rapid changes in temperature (thermal shock) therefore the solder heat resistance specification
(see Soldering Specifications table) should not be exceeded. Subjecting 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.
CLEANING
The components should be cleaned immediately following the soldering operation with vapor degreasers.

SOLVENT RESISTANCE
The coating and marking of the capacitors are resistant to the following test method: IEC 60068-2-45 (method XA).
MOUNTING
If a defined product stop is required for mounting on a PCB, a mechanically formed product stop (kinked or inline wire) or a
mounting tool should be used.
We do not recommend modifying the lead terminals, e.g. bending or cropping. This action could break the coating or crack the
ceramic insert. If however, the lead must be modified in any way, we recommend support of the lead with a clamping fixture
next to the coating.
OPERATING VOLTAGE
In case the voltage is applied to the circuit, starting as well as stopping, may generate irregular voltage for a transit period
because of resonance or switching. Be sure to use a capacitor with a rated voltage range that includes these irregular voltages.
OPERATING TEMPERATURE AND SELF-GENERATED HEAT
Keep the surface temperature of a capacitor below the upper limit of its rated operating temperature range. Be sure to take into
account the heat generated by the capacitor itself. When the capacitor is used in a high frequency, pulse, or similar application,
it may have self-generated heat due to dielectric dissipation.
Temperature increase due to self-generated heating should not exceed 20 °C while operating at an atmosphere temperature of
25 °C.
When measuring, the surface temperature, make sure that the capacitor is not affected by radiant, conductive and convective
heat by its surroundings. Excessive heat may lead to thermo-mechanical deterioration of the capacitor's characteristics and
reliability.
