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 with 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 sued 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. Leon 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 at infrequent time intervals not exceeding 5.5minutes with a limiting resistance of 1k
Ω. 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

(8)Surge Voltage
The capacitor 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, tec.
(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 , 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 while selecting a capacitor for high- frequency 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 , 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.
(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.
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.
(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
before usage.
(d)Standard aluminum electrolytic capacitors are not designed to withstand multiple reflow processes. Please consult
(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.

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.
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.
recommend replacing the capacitors if any of the abovementioned items fail to meet specifications.
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,
chlorine, ammonium, etc. nor to acidic or alkaline solutions.
