Aluminum Electrolytic Capacitor
1.3 Common Application Conditions to Avoid
The following misapplication load conditions will
cause rapid deter ioration to capacitor electr ical
p a r a m e t e r s. l n a d d i t i o n , ra p i d h e a t i n g a n d g a s
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.
The vinyl sleeve of the capacitor can be damaged
i f s o l d e r p a s s e s t h r o u g h a l e a d h o l e 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 resuIt in premature capacitor failure due to
short or open circuit, increased leakage current,
or electrolyte leakage.
(1) Reverse Voltaqe
DC capacitors have polarity. Verify correct polarity
before inser tion. For circuits with changing or
uncertain polarity,use DC bipolar capacitors. DC
bipolar capacitors are not suitable for use in AC
circuits.
(4)Land/Pad Pattern
The circuit board land/pad pattern size for chip
capacitors is specified in the following table.
(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.
[ Table of Board Land Size vs. Capacitor Size ]
(3) Overvoltage
c
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 vo l t a g e does not
exceed the rated voltage.
b
(4) Ripple Current
(1) Capacitors Connected in Parallel
The circuit resistance can closely approximate the
ser ies resistance of the capacitor causing an
imbalance of ripple current loads w i t h in the
capacitors. Careful design of wiring methods can
minimize the possibility of excessive ripple currents
applied to a capacitor.

F(φ8 x 10.2L)
G(φ10 x 10.2L)
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.

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.
(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
u n d e r t h e c a p a c i t o r by c a p i l l a r y a c t i o n a n d
shortcircuit the anode and cathode terminals.
(2) Circuit Board Hole Positioning
Design, Specifications are subject to change without notice. Ask factory for technical specifications before purchase and/or use.

(5)Clearance for Case Mounted Pressure
Relief Vents
2. Capacitor Handling Techniques
2.1 Considerations Before Using
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 released 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.
1.7 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 s l e e v i n g may split or crack if immersed into
solvents such as toluene or xylene, and then exposed
to high temperatures.
(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.
2.2 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) O b s e r v e t e m p e r a t u r e a n d t i m e s o l d e r i n g
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.

2.4
Flow Soldering
(1) Don not immerse the c a p a c i t o r 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
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
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.
(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.

can p e r m e a t e t h e s e a l a n d c a u s e i n t e r n a l
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 b e t w e e n 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.

(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.
(1) I f t h e p r e s s u r e r e l i e f v e n t o f t h e c a p a c i t o r
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
2.9 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.
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 Ω, current limiting
resistor for a time period of 30 minutes.
5.1 Environmental Conditions (Storage)
3. Precautions for using capacitors
3.1 Environmental Conditions
C a p a c i t o r s s h o u l d not b e u s e d i n t h e f o l l o w i n g
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) H i g h h u m i d i t y c o n d i t i o n s w h e r e w a t e r c o u l d
condense on the capacitor.

Aluminum Electrolytic Capacitor
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.
● 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.
Refer to this Technical Report for additional details.
