"Mounting guidelines"
Resistance to
vibration
Do not exceed the tested ability to withstand
vibration. The capacitors are tested to
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".

"Resistance to vibration"
Soldering Do not exceed the specified time or temperature
limits during soldering.
1 "Soldering"
Cleaning Use only suitable solvents for cleaning capacitors. 2 "Cleaning"
Embedding of
capacitors in
finished assemblies
When embedding finished circuit assemblies in
plastic resins, chemical and thermal influences
must be taken into account.
Caution: Consult us first, if you also wish to
embed other uncoated component types!

Display of ordering codes for EPCOS products
The ordering code for one and the same product can be represented differently in data sheets,
data books, other publications and the website of EPCOS, or in order-related documents such as
shipping notes, order confirmations and product labels. The varying representations of the or-
dering codes are due to different processes employed and do not affect the specifications
of the respective products. Detailed information can be found on the Internet under
www.epcos.com/orderingcodes.
