Precautions and Guidelines for Aluminum Electrolytic Capacitors
1. Guidelines for Circuit Design (General / Application
guidelines for using electrolytic capacitors)
Selecting of a right capacitor is a key to a good circuit design.
(1) Polarity
Most of the aluminum electrolytic capacitors are polarized.
Therefore, they must be installed with the correct polarity. Usage in
the reverse polarity results into a short-circuit condition that may
damage or even explode the capacitor. In addition, it may influence
circuit functionality. A bi-polar electrolytic capacitor should be
installed when polarity across a capacitor is unstable / reversible. It
should be, however, noted that usage of both polar and bi-polar
capacitors are limited to DC applications. They must NOT be used
for AC application.
(2) Operating Voltage
Applied DC voltage must not exceed rated voltage of the capacitor.
Applying higher voltage than its rated voltage across a capacitor
terminals cause overheating due to higher leakage currents and
capacitor dielectric/insulation deterioration that will ultimately affect
a capacitor’s performance. The device, however, is capable of
working under short-time transient voltages such as DC transients
and peak AC ripples. Reverse voltages higher than 1 Volt within a
specified temperature limit or AC voltages are not permissible.
Overall, using capacitors at recommended operating voltages can
prolong its lifespan. Note that the result of DC voltage overlapped
with peak ripple voltage should not exceed rated voltage.
(3) Ripple Current
One of the key functions of any capacitor is removal of the ripple
current i.e. the RMS value of AC flowing through a capacitor. But,
a ripple current higher than rated ripple current will drop resultant
capacitance, cause undue internal heating and thus reduces life
span of the capacitor. In extreme cases, internal high temperature
will cause the pressure relief vent to operate while destroying the
device. Overall, it is important to note that an electrolytic capacitor
must be used within a permissible range of ripple current.
Indicators like temperature coefficient of allowable ripple current
are generally used to determine life expectancy of the capacitor,
but to avoid related complex calculations and for the sake of
simplicity, we haven’t provided temperature coefficient in the
catalogue. But it offers key indicators like maximum operating
temperature for calculation of life expectancy at a given
temperature.
(4) Operating Temperature
Capacitors should be used within a permissible range of operating
temperatures. Using capacitor at a higher temperature than
maximum rated temperature will considerably shorten its life. In
the worst-case scenario, high temperature can cause pressure
relief vent to operate and the device will get destroyed. Using
capacitors at an ambient room temperature assure their longer life.
(5) Leakage Current
Leakage current flows through a capacitor when DC voltage is
applied across it. Leakage current varies with changes in ambient
temperature and applied DC voltage level and its time of
application. Overvoltage situation, presence of moisture, and
thermal stresses, especially occurring during the soldering process
can enhance leakage current. Initial leakage current is usually
higher and does not decrease until voltage is applied for a certain
period of time. It is recommended to keep initial leakage current
within specified levels.
(6) Charge and Discharge
Regular electrolytic capacitors are not suitable for rapid
charging/discharging circuits. Such usage may either cause
reduction in overall capacitance or damage due to overheating.
Lelon provides special assistance for selecting appropriate
capacitors for rapid charging/discharging circuits.
(7) Surge Voltage
The Surge voltage rating is referred as the maximum DC
overvoltage that may be applied to an electrolytic capacitor for a
short time interval of 30 seconds at infrequent time intervals not
exceeding 5.5minutes with a limiting resistance of 1kΩ. Unless
otherwise described on the catalogue or product specifications,
please do not apply a voltage exceeding the capacitor’s voltage
rating. The rated surge voltages corresponding to rated voltages of
electrolytic capacitors are presented as follows:

(8) Condition of Use
The capacitors shall NOT be exposed to:
(a) Fluids including water, saltwater spray, oil, fumes, highly humid
or condensed climates, etc.
(b) Ambient conditions containing hazardous gases/fumes like
hydrogen sulfide, sulfurous acid, nitrous acid, chlorine or
bromine gas, ammonia, etc.
(c) Exposed to ozone, ultraviolet rays and radiation.
(d) Severe vibrations or physical shocks that exceeds the
specifications mentioned in this catalogue.
(9) Circuit Design Consideration
(a) Please ensure whether application, operating and mounting
conditions satisfy the conditions specified in the catalog before
installation of a capacitor. Please consult Lelon, if any of the
conditions are beyond the conditions specified in the catalog.
(b) Heat-generating components or heat sinks should not be
placed closer to Aluminum electrolytic capacitors on the PCB to
avoid their premature failure. A cooling system is recommended
to improve their reliable working.
(c) Electrical characteristics and performance of aluminum
electrolytic capacitors are affected by variation of applied
voltage, ripple current, ripple frequency and operating
temperature. Therefore, these parameters shall not exceed
specified values in the catalog.
(d) Aluminum capacitors may be connected in the parallel fashion
for increasing total capacitance and/or for achieving higher
ripple current capability. But, such design may cause unequal
current flow through each of the capacitors due to differences in
their impedances.
(e) When two or more capacitors are connected in series, voltage
across each capacitor may differ and fall below the applied
voltage. A resistor should be placed across each capacitor so
as to match applied voltage with voltage across a capacitor.
(f) Please consult Lelon while selecting a capacitor for highfrequency switching circuit or a circuit that undergoes rapid
charging/ discharging
(g) Standard outer sleeve of the capacitor is not a perfect electrical
insulator therefore is unsuitable for the applications that
requires perfect electrical insulation. Please consult Lelon, if
your application requires perfect electrical insulation.
(h) Tilting or twisting capacitor body is not recommended once it is
soldered to the PCB.
2. Caution for Assembling Capacitors
(1) Mounting
(a) Aluminum electrolytic capacitors are not recommended to reuse in other circuits once they are mounted and powered in a
circuit.
LELON ELECTRONICS CORP.
VUA-APR-12
(b) Aluminum electrolytic capacitors may hold static charge
between its anode and cathode, which is recommended to be
discharged through a 1kΩ resistor before re-use.
(c) A long storage of capacitors may result into its insulation
deterioration. This can lead to a high leakage current when
voltage is applied that may damage the capacitor. Capacitors
following a long storage period must undergo voltage
treatment/re-forming.
Capacitors are charged by applying rated DC voltage through a
resistor of 1kΩ in series at least for an hour. It is recommended
to increase applied voltage gradually using a voltage regulator
unit once capacitors are assembled on the board. The charging
should be followed by discharging through a 1KΩ resistor.
(d) Please check capacitor rated voltage before mounting.
(e) Please check capacitor polarity before mounting.
(f) Please don’t drop capacitor on the floor / hard object.
(g) Please don’t deform the capacitor during installation.
(h) Please confirm whether the lead spacing of the capacitors
match with its pad spacing / footprint on PCB prior to
installation.
(i) Please avoid excessive mechanical shocks to capacitor during
the auto-insertion process, inspection or centering operations.
(j) Please don’t place any wiring or circuit over the capacitor’s
pressure relief vent. The pressure relief vent may fail to open if
adequate clearance space is not provided. Following table
shows minimum clearance space required for different case
diameters.

(2) Soldering
(a) Please confirm that soldering conditions, especially
temperature and contact time are within our specifications. Dip
or flow soldering temperature should be limited at 260 ± 5℃ for
10 ± 1 sec while manual soldering using soldering iron should
be limited at 350 ± 5℃ for 3 +1/-0 seconds. Please do not dip
capacitor body into molten solder. A capacitor’s life will be
negatively affected if these conditions are violated.
(b) Storage of capacitors in high humidity conditions is likely to
affect the solder-ability of lead wires and terminals.

3. Maintenance Inspection
Periodical inspection of aluminum capacitors is absolutely necessary,
especially when they are used with industrial equipment. The following
items should be checked:
(1) Appearance: Bloated, vent operated, leaked, etc.
(2) Electrical characteristic: Capacitance, Tanδ, leakage current, and
other specified items listed in specification.
Lelon recommend replacing the capacitors if any of the
abovementioned items fail to meet specifications.
(c) Reflow soldering should NOLY be used for SMD type
capacitors. The temperature and duration shall not exceed the
specified temperature and duration in the specification. If the
temperature or duration is higher than the value specified,
please consult Lelon before usage.
(d) Standard aluminum electrolytic capacitors are not designed to
withstand multiple reflow processes. Please consult Lelon if
repeated reflowing is unavoidable.
(e) Incorrect mounting on PCB with improper external strength
applied on its lead wires or capacitor body after soldering may
damage a capacitor’s internal structure, cause short circuit, or
lead to high leakage current issues. Do not bend or twist the
capacitor body after soldering. Referring to the drawings below
only case (i) is recommended.
(i) Correct soldering
(ii) Hole-to-hole spacing on PCB differs from the lead space of
lead wires.
(iii) Lead wires are bent after soldering.
(iv) Capacitor body doesn’t stand vertical on PCB after
soldering.
(3) Cleaning Circuit Boards after Soldering
(a) Following chemicals are not recommended for cleaning:
Solvent containing halogen ions, Alkaline solvent, Xylene,
Acetone, Terpene, petro-based solvent.
(b) Recommended cleaning conditions:
Fatty-alcohol - Pine Alpha ST-100S, Clean Through-750H and
IPA (isopropyl alcohol) are examples of the most acceptable
cleaning agents. Temperature of the cleaning agent must not
exceed 60℃. Flux content in the cleaning agents should be
limited to 2 Wt. %. Overall length of cleaning process (e.g.,
immersion, ultrasonic or other) shall be within 5 minutes (5 ~
7mm height within 3 minutes). CFC substitute cleaning agents
such as AK225AES can also be used for cleaning. In this case,
its temperature shall not exceed 40 C and cleaning process
(e.g., immersion, ultrasonic or other) shall be completed within
2 ~ 3 minutes. After cleaning capacitors should be dried with
hot air for at least 10 minutes along with the PCB. Temperature
of hot air shall not exceed maximum category temperature of
the capacitor. Insufficient drying may cause appearance
defects, sleeve shrinkage, and bottom-plate bulging. However,
usage of this CFC substitute must completely regulated for
protection of environment.

4. Storage
(1) The most suitable conditions for aluminum capacitor storage are 5
℃ ~ 35℃ and indoor relative humidity less than 75%. High
temperature and/or humidity storage is detrimental to the
capacitors.
(2) Capacitors shall not be stored in wet or damp atmospheres
containing water, brine, fumes or oil.
(3) Capacitors storage area shall neither be exposed to hazardous
gases such as hydrogen sulfide, sulfurous acid, nitrous acid,
