Mounting considerations
The internal structure of single-ended capacitors might be damaged if excessive force is applied to the lead wires.
Stresses like push, pull, bend, etc. might cause increased leakage current, intermittent capacitance, electrolyte leak-
age or open/short circuit, due to rupture of terminals or internal elements.
The following actions should be avoided:
ꢀ Moving the capacitor after soldering to the PC board.
ꢀ Picking up the PC board by holding the soldered capacitor.
ꢀ Inserting the capacitor on the PC board with a hole space different to the specified lead space.

Cautions and warnings
Personal safety
The electrolytes used by EPCOS have not only been optimized with a view to the intended application, but also
with regard to health and environmental compatibility. They do not contain any solvents that are detrimental to
health, e.g. dimethyl formamide (DMF) or dimethyl acetamide (DMAC).
Furthermore, part of the high-voltage electrolytes used by EPCOS are self-extinguishing. They contain flame-
retarding substances which will quickly extinguish any flame that may have been ignited.
As far as possible, EPCOS does not use any dangerous chemicals or compounds to produce operating elec-
trolytes. However, in exceptional cases, such materials must be used in order to achieve specific physical and
electrical properties because no safe substitute materials are currently known. However, the amount of danger-
ous materials used in our products has been limited to an absolute minimum. Nevertheless, the following rules
should be observed when handling Al electrolytic capacitors:
ꢀ Any escaping electrolyte should not come into contact with eyes or skin.
ꢀ If electrolyte does come into contact with the skin, wash the affected parts immediately with running water.
If the eyes are affected, rinse them for 10 minutes with plenty of water. If symptoms persist, seek medical treat-
ment.
ꢀ Avoid breathing in electrolyte vapor or mists. Workplaces and other affected areas should be well ventilated.
Clothing that has been contaminated by electrolyte must be changed and rinsed in water.
Product safety
ꢀ Make sure that polar capacitors are connected with the right polarity.
ꢀ Voltages polarity clashes should be prevented by connecting a diode.
ꢀ Do not damage the insulating sleeve, especially when ring clips are used for mounting.
ꢀ Do not exceed the upper category temperature (UCT).
ꢀ Make periodic inspections of the capacitors. Before the inspection, make sure that the power supply
is turned off and carefully discharge the electricity of the capacitors.
ꢀ Do not apply any mechanical stress to the capacitor terminals.
ꢀ The internal structure of single-ended capacitors may be damaged if excessive force is applied to
the lead wires.
ꢀ Avoid any compressive, tensile or flexural stress.
ꢀ Do not move the capacitor after soldering to the PC board.
ꢀ Do not pick up the PC board by the soldered capacitor.
ꢀ Do not insert the capacitor on the PC board with a hole space different to the lead space specified.
ꢀ Do not exceed the specified time or temperature limits during soldering.
ꢀ Capacitors should be dipped in solder for less than 10 seconds.
ꢀ Do not allow halogenated hydrocarbons to come into contact with aluminum electrolytic capacitors.
ꢀ Avoid external energy, such as fire or electricity.
ꢀ Avoid overload of the capacitors.
Failure to follow cautions and warnings may result in the worst case in premature failure, bursting and fire.

electrolytic capacitors. These sol-
vents may dissolve or decompose
the insulating film and reduce the in-
sulating properties to below the per-
missible level. The capacitor seals
may be affected and swell, and the
solvents may even penetrate them.
This will lead to premature compo-
nent failure.
Polarity
Make sure that polar capacitors are
connected with the right polarity. If
the opposite polarity were to be ap-
plied, this would cause an electrolyt-
ic process resulting in the formation
of a dielectric layer on the cathode
foil. In this case strong internal heat
generation and gas emission may
occur and destroy the capacitor.
Polar capacitors do not tolerate a
voltage reversal. Incorrect polarities
of up to 1.5 V are, however, permis-
sible for short periods of time as the
formation of a damaging oxide layer
on the cathode only starts at volt-
ages of this magnitude.
Maintenance
Make periodic inspections for the
capacitors that have been used in
the devices for industrial applica-
tions. Before the inspection, make
that the power supply is turned off
Because of this, measures must be
and carefully discharge the electricity taken to prevent electrolytic capaci-
of the capacitors. To check the
capacitors, make sure of the polarity
when measuring the capacitors by
using a volt-ohm meter, for instance.
Also, do not apply any mechanical
stress to the capacitor terminals.
The following items should be
tors from coming into contact with
the solvents when using halogenat-
ed hydrocarbon solvents to clean
printed circuit boards after soldering
the components, or to remove flux
residues. If it is not possible to pre-
vent the electrolytic capacitors from

Electrical characteristics: leakage
gen-free solvents must be used in
order to eliminate the possibility of
damage.
Reverse voltage
Aluminum electrolytic capacitors are
polar capacitors. Where necessary,
voltages of opposite polarity should
be prevented by connecting a
diode. The diode’s conducting-state
voltage of approximately 0.8 V is
permissible. Reverse voltages ≤1.5 V
are tolerable for a duration of less
than 1 second, but not in continu-
ous or repetitive operation.
current, capacitance, tan ꢀ and other
characteristics prescribed in the
catalogs or product specifications.
If any of the above is found, replace
it or take any other proper measure.
Halogenated hydrocarbons may
cause serious damage if allowed to
come into contact with aluminum
electrolytic capacitors.
Passive flammability
Under the influence of high external
energy, such as fire or electricity, the
flammable parts may get inflamed.
Clause 38 of the relevant specifica-
tion CECC 30000 (Harmonized
System of Quality Assessment for
Electronic Components; Generic
Specification: Fixed Capacitors)
refers to IEC Publication 695-2-2
(Needle Flame Test) for testing the
passive flammability of capacitors.
And in CECC 30000, severities and
requirements for different categories
of flammability are listed. Most of
aluminum electrolytic capacitors
meet the requirements of category C.
Mounting position
Breakdown strength of
insulating sleeves
An overpressure vent ensures that
the gas can escape when the pres-
sure reaches a certain level.
To prevent electrolyte from leaking
out when the gas is “vented”, the
capacitor should be mounted in an
upright position (90°). All of these
mounting positions are intended to
avoid a vent-down installation of the
capacitor.
The minimum breakdown strength of
the insulating sleeve is 2500 VAC or
3500 VDC. A test method for verifying
the breakdown strength of the slee-
ves is described in IEC 60384-4.
In order to ensure full breakdown
strength, care must be taken not to
damage the insulating sleeve, espe-
cially when ring clips are used for
mounting. The insulation can be im-
proved by using an insulating strip.
In such cases, attention must be
paid to any relevant regulations
Active flammability
In rare cases the component may
ignite caused by heavy overload or
some capacitor defect. One reason
could be the following: During the
operation of an aluminum electrolytic
capacitor with nonsolid electrolyte,
there is a small quantity of hydrogen
developed in the component. Under
normal conditions, this gas perme-
ates easily out of the capacitor. But
under exceptional circumstances,
higher gas amounts may develop
and may catch fire if a sparking
would occur at the same time.
As explained above a fire risk can’t
be totally excluded. Therefore, it is
recommended to use special mea-
sures in critical applications (e.g. ad-
ditional encapsulation of the equip-
ment for mining applications).
Mounting of single-ended
capacitors
(e.g. VDE, BSA or UL regulations).
For further information see page 67.
Upper category tempera-
ture (UCT)
Soldering
Excessive time or temperature dur-
ing soldering will affect capacitor’s
characteristics and cause damage
to the insulation sleeve. Capacitors
should be dipped in solder for less
than 10 seconds. Contact of the
sleeve with soldering iron must be
avoided.
The upper category temperature is
the maximum permissible ambient
temperature at which a capacitor
may be continuously operated. If
this limit is exceeded, the capacitor
may fail prematurely.
For some type series, however, op-
eration at temperatures above the
UCT is permissible for short periods
of time. The maximum permissible
operating temperatures are specified
in the data sheets for the individual
type series under "Specifications
