1.Circuit Design
1.1 Operating Temperature and Frequency
Electrolytic capacitor electrical parameters are normally specified at 20℃ temperature and 120Hz frequency.
These parameters vary with changes in temperature and frequency. Circuit designers should take these changes
into consideration.
(1) Effects of operating temperature on electrical parameters
a) At higher temperatures, leakage current and capacitance increase while equivalent series resistance (ESR)
decreases.
b) At lower temperatures, leakage current and capacitance decrease while equivalent series resistance (ESR)
increases.
(2) Effects of frequency on electrical parameters
a) At higher frequencies capacitance and impedance decrease while tanδ increases.
b) At lower frequencies, ripple current generated heat will rise due to an increase in equivalent series resistance
(ESR).
1.2 Operating Temperature and Life Expectancy
See the file: Life calculation of aluminum electrolytic capacitor
1.3 Common Application Conditions to Avoid
The following misapplication load conditions will cause rapid deterioration to capacitor electrical parameters. In
addition, rapid heating and gas generation within the capacitor can occur causing the pressure relief vent to
operate and resultant leakage of electrolyte. Under Leaking electrolyte is combustible and electrically
conductive.

(1) Reverse Voltage
DC capacitors have polarity. Verify correct polarity before insertion. For circuits with changing or uncertain
polarity, use DC bipolar capacitors. DC bipolar capacitors are not suitable for use in AC circuits.
(2) Charge / Discharge Applications
Standard capacitors are not suitable for use in repeating charge / discharge applications. For charge / discharge
applications consult us and advise actual conditions.
(3) Over voltage
Do not apply voltages exceeding the maximum specified rated voltage. Voltages up to the surge voltage rating are
acceptable for short periods of time. Ensure that the sum of the DC voltage and the superimposed AC ripple
voltage does not exceed the rated voltage.
(4) Ripple Current
Do not apply ripple currents exceeding the maximum specified value. For high ripple current applications, use a
capacitor designed for high ripple currents or contact us with your requirements.
Ensure that allowable ripple currents superimposed on low DC bias voltages do not cause reverse voltage
conditions.
1.4 Using Two or More Capacitors in Series or Parallel
(1) Capacitors Connected in Parallel
The circuit resistance can closely approximate the series resistance of the capacitor causing an imbalance of ripple
current loads within the capacitors. Careful design of wiring methods can minimize the possibility of excessive
ripple currents applied to a capacitor.
(2) Capacitors Connected in Series
Normal DC leakage current differences among capacitors can cause voltage imbalances. The use of voltage
divider shunt resistors with consideration to leakage current can prevent capacitor voltage imbalances.
1.5 Capacitor Mounting Considerations
(1) Double Sided Circuit Boards
Avoid wiring pattern runs, which pass between the mounted capacitor and the circuit board.
When dipping into a solder bath, excess solder may collect under the capacitor by capillary action and short circuit
the anode and cathode terminals.
(2)Circuit Board Hole Positioning
The vinyl sleeve of the capacitor can be damaged if solder passes through a lead hole for subsequently processed
parts. Special care when locating hole positions in proximity to capacitors is recommended.
(3)Circuit Board Hole Spacing
The circuit board holes spacing should match the capacitor lead wire spacing within the specified tolerances.
Incorrect spacing can cause excessive lead wire stress during the insertion process. This may result in premature
capacitor failure due to short or open circuit, increased leakage current, or electrolyte leakage.

(4) Clearance for Case Mounted Pressure Relief vents
Capacitors with case mounted pressure relief vents require sufficient clearance to allow for proper vent operation.
The minimum clearances are dependent on capacitor diameters as proper vent operation. The minimum clearances
are dependent on capacitor diameters as follows.
φ6.3~φ16mm:2mm minimum, φ18~φ35mm:3mm minimum, φ40mm or greater:5mm minimum.
(5) Clearance for Seal Mounted Pressure Relief Vents
A hole in the circuit board directly under the seal vent location is required to allow proper release of pressure.
(6) Wiring Near the Pressure Relief Vent
Avoid locating high voltage or high current wiring or circuit board paths above the pressure relief vent. Flammable, high
temperature gas exceeding 100℃ may be released which could dissolve the wire insulation and ignite.
(7) Circuit Board patterns Under the Capacitor
Avoid circuit board runs under the capacitor as electrolyte leakage could cause an electrical short.
(8) Screw Terminal Capacitor Mounting
Do not orient the capacitor with the screw terminal side of the capacitor facing downwards.
Tighten the terminal and mounting bracket screws within the torque range specified in the specification.
1.6 Electrical Isolation of the Capacitor
Completely isolate the capacitor as follows.
(1) Between the cathode and the case (except for axially leaded B types) and between the anode terminal and other
circuit paths
(3) Between the extra mounting terminals (on T types) and the anode terminal, cathode terminal, and other circuit
paths.
1.7 The Product characteristic should take the sample as the standard.
1.8 Capacitor Sleeve
The vinyl sleeve or laminate coating is intended for marking and identification purposes and is not meant to
electrically insulate the capacitor.
The sleeve may split or crack if immersed into solvents such as toluene or xylene, and then exposed to high
temperatures.
CAUTION!
Always consider safety when designing equipment and circuits. Plan for worst case failure modes such as short
circuits and open circuits which could occur during use.
(1) Provide protection circuits and protection devices to allow safe failure modes.
(2) Design redundant or secondary circuits where possible to assure continued operation in case of main circuit
failure.

2.Capacitor Handling Techniques
2.1 Considerations Before Using
(1) Capacitors have a finite life. Do not reuse or recycle capacitors from used equipment.
(2) Transient recovery voltage may be generated in the capacitor due to dielectric absorption. If required, this voltage
can be discharged with a resistor with a value of about 1kΩ.
(3) Capacitors stored for long periods of time may exhibit an increase in leakage current. This can be corrected by
gradually applying rated voltage in series with a resistor of approximately 1kΩ.
(4) If capacitors are dropped, they can be damaged mechanically or electrically. Avoid using dropped capacitors.
(5) Dented or crushed capacitors should not be used. The seal integrity can be compromised and loss of electrolyte /
shortened life can result.
2.2 Capacitor Insertion
* (1) Verify the correct capacitance and rated voltage of the capacitor.
* (2) Verify the correct polarity of the capacitor before inserting.
* (3) Verify the correct hole spacing before insertion (land pattern size on chip type) to avoid stress on the terminals.
(4) Ensure that the auto insertion equipment lead clinching operation does not stress the capacitor leads where they
enter the seal of the capacitor.
For chip type capacitors, excessive mounting pressure can cause high leakage current, short circuit, or
disconnection.
2.3 Manual Soldering
(1) Observe temperature and time soldering specifications or do not exceed temperatures of 400 ℃ for 3
seconds or less.
(2) If lead wires must be formed to meet terminal board hole spacing, avoid stress on the lead wire where it
enters the capacitor seal.
(3) If a soldered capacitor must be removed and reinserted, avoid excessive stress to the capacitor leads.
(4) Avoid touching the tip of the soldering iron to the capacitor, to prevent melting of the vinyl sleeve.
2.4 Flow Soldering
(1) Do not immerse the capacitor body into the solder bath as excessive internal pressure could result.
(2) Observe proper soldering conditions (temperature, time, etc.) Do not exceed the specified limits.
(3) Do not allow other parts or components to touch the capacitor during soldering.
2.5 Other Soldering Considerations
Rapid temperature rises during the preheat operation and resin bonding operation can cause cracking of the
capacitor vinyl sleeve.
For heat curing, do not exceed 150℃ for a maximum time of 2 minutes.

2.6 Capacitor Handling after Solder
(1). Avoid movement of the capacitor after soldering to prevent excessive stress on the lead wires where they enter
the seal.
(2). Do not use capacitor as a handle when moving the circuit board assembly.
(3). Avoid striking the capacitor after assembly to prevent failure due to excessive shock.
2.7 Circuit Board Cleaning
* (1 ) Circuit boards can be immersed or ultrasonically cleaned using suitable cleaning solvents for up 5 minutes
and up to 60℃ maximum temperatures. The boards should be thoroughly rinsed and dried.
The use of ozone depleting cleaning agents is not recommended in the interest of protecting the environment.
* (2) Avoid using the following solvent groups unless specifically allowed for in the specification;
.
Halogenated cleaning solvents: except for solvent resistant capacitor types, halogenated solvents can permeate
the seal and cause internal capacitor corrosion and failure. For solvent resistant capacitors, carefully follow the
temperature and time requirements of the specification. 1-1-1 trichloroethane should never be used on any
aluminum electrolytic capacitor.
.
Alkali solvents
: could attack and dissolve the aluminum case.
.
Petroleum based solvents: deterioration of the rubber seal could result.
. Xylene
: deterioration of the rubber seal could result.
. Acetone
: removal of the ink markings on the vinyl sleeve could result.
* (3 ) A thorough drying after cleaning is required to remove residual cleaning solvents which may be trapped
between the capacitor and the circuit board. Avoid drying temperatures, which exceed the maximum rated
temperature of the capacitor.
* (4) Monitor the contamination levels of the cleaning solvents during use by electrical conductivity, pH, specific
gravity, or water content. Chlorine levels can rise with contamination and adversely affect the performance of the
capacitor.
Please consult us for additional information about acceptable cleaning solvents or cleaning methods.
2.8 Mounting Adhesives and Coating Agents
When using mounting adhesives or coating agents to control humidity, avoid using materials containing
halogenated solvents. Also, avoid the use of chloroprene based polymers.
After applying adhesives or coatings, dry thoroughly to prevent residual solvents from being trapped between the
capacitor and the circuit board.
3. Precautions for using capacitors
3.1 Environmental Conditions
Capacitors should not be stored or used in the following environments.
* (1) Temperature exposure above the maximum rated or below the minimum rated temperature
of the capacitor.
* (2) Direct contact with water, salt water, or oil.
* (3) High humidity conditions where water could condense on the capacitor.

(4) Exposure to toxic gases such as hydrogen sulfide, sulfuric acid, nitric acid chlorine, or ammonia.
(5) Exposure to ozone, radiation, or ultraviolet rays.
(6) Vibration and shock conditions exceeding specified requirements.
3.2 Electrical Precautions
(1) Avoid touching the terminals of the capacitor as possible electric shock could result. The exposed aluminum
case is not insulated and could also cause electric shock if touched.
(2) Avoid short circuit the area between the capacitor terminals with conductive materials including liquids such
as acids or alkaline solutions.
4. Emergency Procedures
(1) If the pressure relief vent of the capacitor operates, immediately turn off the equipment and disconnect form
the power source. This will minimize additional damage caused by the vaporizing electrolyte.
(2) Avoid contact with the escaping electrolyte gas which can exceed 100℃ temperatures.
If electrolyte or gas enters the eye, immediately flush the eyes with large amounts of water.
If electrolyte or gas is ingested by month, gargle with water.
If electrolyte contacts the skin, wash with soap and water.
5. Long Term Storage
The characteristics of aluminum electrolytic capacitors degrade when stored in a static condition for long periods of
time. The rate of deterioration depends upon temperature and humidity.
Capacitors should be stored at the temperature of 5℃ to 35℃, the humidity of less than 75% RH and out of direct
sunlight.
Leakage current of a capacitor increases with long storage times. The aluminum oxide film deteriorates as a function
of temperature and time. If used without reconditioning, an abnormally high current will be required to restore the
oxide film. This current surge could cause the circuit or the capacitor to fail.
After one year, a capacitor should be reconditioned by applying rated voltage in series with a 1000Ω,current
limiting resistor for a time period of 30 minutes .
5.1 Environmental Conditions
The capacitor shall be not use in the following condition:
(1) Temperature exposure above the maximum rated or below the minimum rated temperature of the capacitor.
(2) Direct contact with water, salt water, or oil.
(3) High humidity conditions where water could condense on the capacitor.
(4) Exposure to toxic gases such as hydrogen sulfide, sulfuric acid, nitric acid, chlorine, or ammonia.

6. Capacitor Disposal
*
*
When disposing of capacitors, use one of the following methods.
Incinerate after crushing the capacitor or puncturing the can wall (to prevent explosion due to internal pressure
rise). Capacitors should be incinerated at high temperatures to prevent the release of toxic gases such as chlorine
from the polyvinyl chloride sleeve, etc.
Dispose of as solid waste.
NOTE: Local laws may have specific disposal requirements, which must be followed.
