X2 / 305 V AC
Cautions and warnings
Do not exceed the upper category temperature (UCT).
Do not apply any mechanical stress to the capacitor terminals.
Avoid any compressive, tensile or flexural stress.
Do not move the capacitor after it has been soldered to the PC board.
Do not pick up the PC board by the soldered capacitor.
Do not place the capacitor on a PC board whose PTH hole spacing differs from the specified
lead spacing.
Do not exceed the specified time or temperature limits during soldering.
Avoid external energy inputs, such as fire or electricity.
Avoid overload of the capacitors.
The table below summarizes the safety instructions that must always be observed. A detailed de-
scription can be found in the relevant sections of the chapters "General technical information" and
"Mounting guidelines".

Safety information
Reference chapter
"General technical
information"
Make sure that capacitors are stored within the 4.5
specified range of time, temperature and humidity "Storage conditions"
conditions.
Avoid external energy, such as fire or electricity 5.3
(passive flammability), avoid overload of the
"Flammability"
capacitors (active flammability) and consider the
flammability of materials.
Do not exceed the tested ability to withstand
vibration. The capacitors are tested to
5.2
"Resistance to vibration"
IEC 60068-2-6.
EPCOS offers film capacitors specially designed
for operation under more severe vibration regimes
such as those found in automotive applications.
Consult our catalog "Film Capacitors for
Automotive Electronics".
