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
subject to aging see general information (www.vishay.com/doc?23140).

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.
When soldering radial leaded ceramic capacitors with a soldering iron, it should be performed under the following conditions
and should not exceed:
• Maximum temperature of iron-tip: 400 °C
• Maximum soldering iron wattage: 50 W
• Maximum soldering time: 3.5 s
Failure to follow the above cautions may result, in worst case, in short circuit or cause fuming or thermo-mechanical damage
when the product is used.
Leaded ceramic capacitors are not designed for reflow process or dipping the body into a solder melt.
CLEANING
The components should be cleaned immediately following the soldering operation with vapor degreasers.
CLEANING (ULTRASONIC CLEANING)
To perform ultrasonic cleaning, observe the following conditions:
• Maximum rinse bath capacity output: 20 W/liter
• Maximum rinsing time: 300 s
• Do not vibrate the PCB/PWB directly
• Excessive ultrasonic cleaning may lead to mechanical damage
SOLVENT RESISTANCE
The coating and marking of the capacitors are resistant to the following test method:
IEC 60068-2-45 (method XA)
MOUNTING
We do not recommend modifying the lead terminals, e.g. bending or cropping. This action could break the coating or crack the
ceramic insert. In order to avoid such failures we are offering different lead wire designs (e.g. straight, inline, inside crimp,
outside crimp etc.) If however, the lead must be modified in any way, we recommend support of the lead with a clamping fixture
next to the coating. If a defined product stop is required for mounting on a PCB, a mechanically formed product stop or a
mounting tool should be used.

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.
