Application Guidelines
1. Circuit Design
Ensure that operational and mounting conditions follw the specified conditions detailed in the catalog and specification sheets.
1.1 Operating Temperature and Frequency
Electrolytic capacitor electrical parameters are normally specified at 20°C temperature and 120Hz frequency. These p a rameter s 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 tan δ 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
(1) Expected life is affected by operating temperature.
Generally, each 10 °C reduction in temperature will double the expected life. Use capacitors at the lowest possible temperature below the maximum guaranteed temperature. (2) If operating conditions exceed the maximum guaranteed limit, rapid eIectrical parameter deterioration will occur, and irreversible damage will result. Check for maximum capacitor operating tempera­ tures including ambient temperature, internal capacitor temperature rise caused by ripple current, and the effects of radiated heat from power transistors, IC?s or resistors. Avoid placing components which could conduct heat to the capacitor from the back side of the circuit board. (3)The formula for calculating expected Iife at lower operating temperatures is as fllows;
T1-T2
L
2 = L1 x 2 where,
1: Guaranteed life (h) at temperature, T1° C
L L
2: Expected life (h) at temperature,T2°C
T
1: Maximum operating temperature (°C)
T
2: Actual operating temperature, ambient
temperature + temperature rise due to ripple currentheating(°C) A quick eference capacitor guide for estimating exected life is included for your reference.

1.3 Common Application Conditions to Avoid
The following misapplication load conditions will cause rapid deterioration to capacitor electrical parameters. ln addition, rapid heating and gas generation within the capacitor can occur causing the pressure relief vent to operate and resuItant leakage of electrolyte. Under extreme conditions, explosion and fire could result. Leakinq electrolyte is combustible and electrically conductive.
(1) Reverse Voltaqe
DC capacitors have polarity. Verify correct polarity
before insertion. For circuits with chan ging or uncertain polarity,use DC bipolar capacitors. DC bipolar capacitors are not suitable for use in AC circuits.
(2) Charqe/Discharqe Applications
Standard capacitors are not suitable for use in
repeating charge/discharge applications. For charqe/discharqe applications consult us and advise actual conditions.
(3) Overvoltage
Do not appIy voltaqes exceeding the maximum
specified rated voltages. Voltage 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 rippIe 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 w ithin 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 currents, can prevent capacitor voltage imbaIances.
1.5 Capacitor Mounting Considerations
(1) DoubIe - 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 capillar y action and
shortcircuit the anode and cathode ter minals.
(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 pr oximity 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 resuIt in p remature capacitor failure due to short or open circuit, increased leakage current, or electrolyte leakage.
(4)Land/Pad Pattern
The circuit board land/pad patter n size for chip
capacitors is specified in the following table.

Size A(φ3) B(φ4) C(φ5) D(φ6.3) E(φ8 x 6.2L) F(φ8 x 10.2L) G(φ10 x 10.2L)
Among others, when the size a is wide , back fillet can not be made, decreasing fitting strength.
Decide considering mounting condition, solderability and fitting strength, etc. based on the design standards of your company.

(5)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 follows.
f6.3 to f16 mm : 2 mm minimum, f18 to f35 mm : 3 mm minimum.
f40 mm or greater: 5 mm minimum
(6)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.
(7)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°C may be rel eased which could dissolve the
wire insulation and ignite.
(8)Circuit Board Patterns Under the Capacitor
Avoid circuit board runs under the capacitor as
electrolyte leakage could cause an electrical short.
(9)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.
1.6Electrical Isolation of the Capacitor
Completely isolate the capacitor as follows.
Between the cathode and the case (except for axially leaded B types) and between the anode
terminal and other circuit paths.
Between the extra mounting terminals (on T types)
and the anode terminal, cathode terminal, and
other circuit paths.
1.7Capacitor Sleeve
The vinyl sleeve or laminate coating is intended for mar king and identification purposes and is not meant to electrically insulate the capacitor. The sleeving may split or crack if immersed into solvents such as toluene or xylene, and then exposed to high temperatures.
2. Capacitor Handling Techniques
2.1Considerations 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 1 kΩ.
(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 1 kΩ.
(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.
2.2Capacitor 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.
2.3Manual Soldering
(1) Observe temperature and time soldering
specifications or do not exceed temperatures of 350°C for 3 seconds or less.
(2) If lead wires must be formed to meet terminal
board hole spacing, avoid stress on the leadwire where it enters the capacitor seal.
(3) If a soldered capacitor must be removed and
reinserted, avoid excessive stress to the capacitor leads.
(4) Aviod touching the tip of the soldering iron to the
capacitor, to prevent melting of the vinyl sleeve.
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.
Design, Specifications are subject to change without notice. Ask factory for technical specifications before purchase and/or use. Whenever a doubt about safety arises from this product, please inform us immediately for technical consulation without fail.

2.4 Flow Soldering
(1) Don 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 Reflow Soldering for Chip Capacitors
(1) For reflow, use a thermal conduction system such
as infrared radiation (IR) or hot blast. Vapor heat
transfer systems (VPS) are not recommended. (2) Observe proper soldering conditions (temperature,
time, etc.). Do not exceed the specified limits. (3) Reflow should be performed one time. Consult us
for additional reflow restrictions.

2.6 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°C for a maximum time of 2 minutes.
2.7 Capacitor Handling after Soldering
(1) Avoid movement of the capacitor after soldering
to prevent excessive stress on the leadwires where they enter the seal.
(2) Do not use the capacitor as a handle when
moving the circuit board assembly.
(3) Avoid striking the capacitor after assembly to
prevent failure due to excessive shock.
2.8 Circuit Board Cleaning
(1) Circuit boards can be immersed or ultrasonically
cleaned using suitable cleaning solvents for up to 5 minutes and up to 60°C maximum temperatures. The boards should be thoroughly rinsed and dried. Recommended cleaning solvents include Pine Alpha ST-100S, Sunelec B-12, DK Beclear CW-5790, Aqua Cleaner 210SEP, Cold Cleaner P3-375, Telpen Cleaner EC-7R, Clean-thru 750H, Clean-thru 750L, Clean thru 710M, Techno Cleaner 219, Techno Care FRW-17, Techno Care FRW-1, Techno Care FRV-1, IPA (isopropyl alcohol)

(2) Avoid using the followin g solvent groups unless
specifically allowed for in the specification;
Halogenated cleaning solvents: except for solvent resi stant 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 specificaion. 1-1-1 trichloroe thane should never be used on any aluminium 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 additonal information about acceptable cleaning solvents or cleaning methods.

2.9Mounting 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
3.1Environmental Conditions
Capacitors should not be 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.
3.2Electrical Precautions
(1) Avoid touching the terminals of the capacitor as
possible electric shock could result. The exposed aluminium case is not insulated and could also cause electric shock if touched.
(2)Avoid short circuiting 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 from 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°C temperatures. If electrolyte or gas enters the eye, immediately flush the eye with large amounts of water. If electrolyte or gas is ingested by mouth, gargle with water. If electrolyte contacts the skin, wash with soap and water.
5. Long Term Storage
Leakage current of a capacitor increases with long storage times. The aluminium 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. Capacitor should be reconditioned by applying rated voltage in series with a 1000 , current limiting resistor for a time period of 30 minutes.
5.1Environmental Conditions (Storage)
Capacitors should not be stored in the following environments. (1) Temperature exposure above 35°C or below 15 °C. (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.

6. Capacitor Disposal
Mar. 2005
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.
Local laws may have specific disposal
requirements which must be followed.
The application guidelines above are taken from:
Technical Report EIAJ RCR-2367 issued by the Japan Electronic Industry Association, Inc. ­Guideline of notabilia for aluminium electrolytic capacitors with non-solid electrolytic for use in electronic equipment.
