Device circuits design considerations

1) Confirm installation and operating requirements for the capacitors, then use them within the performance limits prescribed in this catalog or product specifications.

2) Polarity
Capacitors are polarized.
Never apply a reverse voltage or AC voltage. Connecting withwrong polarity will short-circuit or damage the capacitor with thepressure relief vent opening early on. To identify the polarity ofa capacitor, see the relevant diagram in the catalogs or productspecifications, or the polarity marking on the body of thecapacitors.

3) Operating voltage
Do not apply an over-voltage that exceeds a rated voltage
specified for the capacitors.
The total peak value of the ripple voltage plus the DC voltage
must not exceed the rated voltage of the capacitors. Capacitors
do not require voltage derating within the category temperature.
Although capacitors specify a surge voltage that exceeds thefull rated voltage, it does not assure long-term use but limited
use under specific conditions.

4) Ripple current
Do not apply an over current that exceeds the rated ripple current specified for the capacitors. Excessive ripple current will
increase heat production within the capacitors, causing the capacitors to be damaged as follows:• Shorten lifetime• Open pressure relief vent• Short circuit
At the time of low DC bias voltage, reverse voltage may be applied if uses with less than rated ripple current. Please use it as
far as the reverse voltage is not applied. The rated ripple current is specified along with a specific ripple frequency. Where
using the capacitors at any ripple frequency other than thespecified frequency, calculate the allowable ripple current by
multiplying the rated ripple current by a frequency compensation factor (Frequency Multiplier) specified for each productseries.

5) Operating temperature (Category temperature)
Do not apply high temperatures that exceed the upper limit of
the category temperature range specified for the capacitors.
Using the capacitors at temperatures higher than the upper
limit will considerably shorten the lifetime of the capacitors andmake the pressure relief vent open. The temperature, pleaseconfirm the temperature of the capacitors which included theambient temperature of the device, not only the temperature in
the device but also radiant heat of the heating element (powertransistor, resistance) in the apparatus, self heating caused by
the ripple current. Additionally, please do not place heating ele-ment on the back side of the capacitors. In addition, please use
the capacitors within category temperature range because thelife of the capacitors are affected by the operating temperature.
In other words, lowering ambient temperatures will extend the
expected lifetime of the capacitors.

6) Lifetime
Select the capacitors to meet the service life requirements ofdevice.

7) Charging and discharging
Do not use capacitors in circuits intended for rapid charge anddischarge cycle operations.
If capacitors are used in the circuits that repeat a charge anddischarge with a large voltage drop or a rapid charge and discharge at short interval cycle, capacitance will decrease and/or
the capacitors will be damaged by internal heat generation.
Please consult us the capacitors to use for the circuit whererapid charge and discharge is repeated.
Please be careful about rush currents. Recommend to install
protective circuit.

8) Leakage current
The leakage current may increase due to thermal stress suchas reflow soldering. After that, however, the leakage current will
gradually decrease by self-healing action of the dielectric oxide
layer when the capacitors are applied with a voltage less than
the rated voltage within the Category Temperature range. As
the voltage is closer to the rated voltage and the temperature iscloser to the upper limit of Category Temperature range, theleakage current decreases faster.
The leakage current will increase by the following factors,① Soldering② Testing of high temperature exposure with no voltage applied,high temperature/humidity storage, temperature
cycles, etc.

9) Failure mode of capacitors
Non-solid aluminum electrolytic capacitors have a limited lifetime which ends in an open circuit failure mode, in general.
Depending on the product type and operating conditions, thefailure mode may involve in opening of the pressure relief vent.
But it may lead to shot circuit mode failure when capacitor isused in the overload more than the guarantee ranges including
over voltage and the over current.
Failure modes depend on the application conditions that lead to
fail.

Poor Sealing10) Capacitor insulation
The can case of capacitor does not assure electrical insulation.
The outer coating on can case is aimed for indication and does
not assure function of the electrical insulation.
Electrically isolate the outer can case of a capacitor from thenegative terminal, the positive terminal and circuit patterns.

11) Operating conditions
Do not use/expose capacitors to the following conditions:① Direct contact with water, salt water or oil, or high condensation environment.
② Direct sunlight③ Toxic gases such as hydrogen sulfide, sulfurous acid, nitrous acid, chlorine and its compounds, bromine and its
compounds and ammonium.
④ Ozone, ultraviolet rays or radiation.
⑤ Extreme vibration or mechanical shock that exceeds limits inthe catalogs or product specifications.
The standard vibration condition is applicable to JIS C 5101-4.

12) Mounting
Capacitors contain paper separators and electric-conductive
electrolyte that contains organic solvent as main solvent material, both of which are flammable. If the electrolyte leaks onto a
printed circuit board, it can erode the device circuit pattern, may
short-circuit the copper traces, smoke and burn. Make sure ofdesigning a PC board as follows:① Provide clearance space (2mm minimum) over the pressure
relief vent of a capacitor to avoid blocking the correct openingof the pressure relief vent for 10mm case diameter ofcapacitor.
② Do not locate any wire or circuit pattern over the pressure
relief vent of a capacitor.
③ Avoid locating any heat source components near capacitors
or on the opposite side of the PC board under capacitors.
④ Design the solder land on the PC board in accordance withthe catalog or the product specification.
⑤ For radial capacitors, design the terminal holes on the PC
board to fit the terminal dimension of the capacitor.
⑥ Do not print any copper trace under the seal (terminal) sideof a capacitor. When the electrolyte leaks out, it may occur
circuit pattern short-circuit, and tracking or migration.
Copper traces should be 1 mm (preferably 2mm or more)
spaced apart from the side of the capacitor body.
⑦ In designing a double-sided PC board, do not locate any
through-hole via or unnecessary hole underneath a capacitor.

⑧ In designing a double-sided PC board, do not print any circuit pattern underneath a capacitor.

13) Using capacitors for significantly safety-oriented
applications
Consult with us in advance of usage of our products in the following listed applications. ① Aerospace equipment ② Powergeneration equipment such as thermal power, nuclear power
etc. ③ Medical equipment ④ Transport equipment (automobiles, trains, ships, etc.) ⑤ Transportation control equipment ⑥
Disaster prevention / crime prevention equipment ⑦ Highly
publicized information processing equipment ⑧ Submarine
equipment ⑨ Other applications that are not considered general-purpose applications.

14) Others
Design device circuits taking into consideration the following
conditions:① Electrical characteristics of a capacitor depend on the temperature and frequency. In designing the device circuits,
consider the change in the characteristics.
② If using more than one capacitor connected in parallel, design the device circuits to balance the current flow in individual capacitors.
③ If using more than one capacitor connected in series, connect shunting resistors in parallel with the individual capacitors to balance the voltage.

Installation

1 ) Assembling① Do not try to reuse the capacitors once assembled and electrified② Capacitors may have been spontaneously recharged withtime by a recovery voltage phenomenon.
Capacitors may produce recovery voltage higher than aluminum electrolytic capacitors and conductive polymer aluminum solid capacitors. In this case, discharge electricity
through approximately 1kΩ before use.
③ If capacitors have been stored at any conditions more than35°
C and 75%RH for long storage periods of time more thanthe limits specified in the catalogs or product specifications,they may have high leakage current. In this case, makepre-conditioning by applying the rated voltage through a resistor
of approximately 1kΩ.
④ Confirm the rated capacitance and voltage of capacitors

PRECAUTIONS AND GUIDELINES (Conductive Polymer Hybrid)
before installation.
⑤ Confirm the polarity of capacitors before installation.
⑥ Do not try to use the capacitors that were dropped to thefloor and so forth.
⑦ Do not deform the can case of a capacitor.
⑧ Verify that the lead spacing of the capacitor fits the holespacing in the PC board before installing the capacitors.
⑨ Do not apply excessive mechanical force to capacitors morethan the limits prescribed in the catalogs or product specifications. Avoid excessive mechanical force while the capacitors
are in the process of vacuum-picking, placing and positioning
by automatic mounting machines or cutting the lead wires byautomatic insertion machines.

2) Soldering and heat resistance① For soldering using a soldering iron, consider the following
conditions:
Soldering conditions (temperature and time) should be (380
± 10°C, 3 ± 0.5second).
Do not touch the body of a capacitor with the hot tip of thesoldering iron.
② Verify the following when flow soldering:・ Do not dip the body of a capacitor into the solder bath only
dip the terminals in. The soldering must be done on the reverse side of PC board.
・ Soldering conditions（preheat, solder temperature and dipping time）should be within the limits prescribed in the catalog or the product specifications.
・Do not apply flux to any part of capacitors other than their terminals.
・ Make sure the capacitors do not come into contact with anyother components while soldering.
③ For reflow soldering, consider the following conditions:
Soldering conditions (preheat, reflow temperature and time)should be within the limits prescribed in the catalogs or
product specifications.
・ When using the infrared heater and setting its temperatures,
adjust the heating levels taking into consideration that the colorand materials of a capacitor vary in their infrared absorbance.
・The allowable number of reflow passes is specified in the
catalogs or product specifications.
・Please consult us about vapor phase soldering (VPS).
④ Do not try to reuse the capacitors once assembled.
⑤ Only use radial lead type capacitors for ﬂow soldering. The
other type capacitors are not designed for the flow soldering.
⑥ Only use chip type capacitors for reﬂow soldering. The othertype capacitors are not designed for the reflow soldering.

3) Handling after soldering
After soldering the PC board, do not apply the following mechanical stress to the capacitor:① Do not tilt, push down or twist the body of the capacitor.
② Do not grab the body of the capacitor to carry the assembly board.
③ Do not hit anything against the capacitor. When stacking theassembled boards, do not put any of the PC boards or othercomponents against the capacitor.
④ Do not drop the assembled board.

4) Cleaning assembly boards① Do not clean capacitors with the following cleaning agents:• Halogenated solvents: cause capacitor failures due to corrosion.
• Alkali system solvents: corrode (dissolve) the aluminum can case.
• Terpene and petroleum system solvents: deteriorate therubber seal materials.
• Xylene and toluene: deteriorates the rubber seal materials
as well.
• Acetone: erases the markings printed on a capacitor.
Where cleaning is necessary, use only solvent resistant type
capacitors that have been assured for the cleaning within thespecific cleaning conditions prescriber in the catalogs or productspecifications. In particular, carefully set up the conditions forultrasonic cleaning system. Consult us regarding alternative

CFCs or other cleaners before use.
② Where cleaning the capacitors, confirm the following conditions:• Control the contamination (the conductivity, pH, specificgravity, water content, etc.) of the cleaning agents.
• After the cleaning, do not leave the capacitors (assemblyboards) in an environment of cleaning agent-rich or in aclosed container. Sufficiently evaporate the residual cleaning
agent from the assembly boards and the capacitors by forced
hot air at temperatures less than the upper limit of categorytemperature range for more than 10 minutes.
In general, aluminum electrolytic capacitors are sensitive tocontamination of halogen ions (particularly to chlorine ions).
Depending on the properties of the electrolyte and rubber sealmaterials used in a capacitor, the halogen ions lead up to catastrophic failures on the capacitor. Where the inside of a capacitor
has been contaminated with more than a certain amount of halogen ions and the capacitor is in use, the corrosion reaction ofaluminum occurs. The corrosion causes the capacitor to have asignificant increase in leakage current with heat produced,
open the pressure relief vent and become open circuit mode
failure.
Due to global environmental issues (greenhouse effects andother environmental destruction by depletion of the ozone layer),
the conventional cleaning solvents of CFC 113, Trichloroethylene
and 1,1,1-trichloroethylene were replaced by substitutes. The
following are some substitute cleaning agents and allowablecleaning conditions:a) Fatty-alcohol cleaning agents
Pine Alpha ST-100S (Arakawa Chemical)
Clean Through 750H, 750HS and 750J (Kao)[Cleaning conditions]
Either of immersion or ultrasonic cleaning, for a maximumof 10 minutes and at a maximum liquid temperature of
60°C is acceptable. Make sure that the markings on thecapacitor are not rubbed against any other component or
the PC board during cleaning. Note that shower cleaning
affects the markings on the capacitor.
b) Alternative CFCs
AK225AES (Asahi Glass)[Cleaning conditions]
Solvent resistant type capacitors, which were originallydeveloped to intend to resist Freon TE or Freon TES,
are also capable of withstanding any one of immersion,
ultrasonic or vapor cleaning, for a maximum of 5
minutes.
However, this type of cleaning agent is not recommended to use, as the cleaning materials may be banned innear future in view of global environmental issuesc) IPA (Isopropyl Alcohol)
Immersion cleaning with a maximum flux concentration of 2
wt% is acceptable.

5) Adhesives and coating materials① Do not use any adhesive or coating materials containing halogenated solvents.
② Make sure of the following conditions before applying adhesive or coating materials to a capacitor,
・No flux residue nor stain is left between the rubber seal of acapacitor and PC board.
・Dry the capacitor to remove residual cleaning agents before
applying adhesive and coating materials. Do not cover up theentire surface of the rubber seal of the capacitor with adhesives or coating materials.
・Consult us Heating and curing conditions for adhesives andcoating materials.
・Covering up the entire surface of the rubber seal with resin
mold materials will obstruct the normal diffusion of internal

PRECAUTIONS AND GUIDELINES (Conductive Polymer Hybrid)hydrogen gas from a capacitor and result in serious failures.
Also, where the adhesive and coating materials contain alarge amount of halogen ions, the halogen ions will contaminate the inside of the capacitor through the rubber seal materials, causing the capacitor to become a failure.
・ Depending on solvent materials that the adhesive or coating
materials contains, note that the surface of a capacitor may
change in appearance.

6) Fumigation
In exporting or importing electronic devices, they may be exposed to fumigation with halide such as methyl bromide.
Where the capacitors are exposed to halide such as methyl
bromide, the capacitors will be damaged with the corrosion reaction with halogen ions in the same way as cleaning agents.
For the export and import, Nippon Chemi-Con considers using
some packaging method and so forth so that fumigation is not
required. For customers to export or import electronic devices,semi-assembly products or capacitor components, confirm ifthey will be exposed to fumigation and also consider final condition of packaging. (Note that either cardboard or vinyl package has a risk of fumigation gas penetration.)3

Precautions during operation of devices(1) Never touch the terminals of a capacitor directly with barehands.
(2) Do not short-circuit between the capacitor terminals with anything conductive. Also, do not spill any conductive liquidsuch as acid or alkaline solution over a capacitor.
(3) Confirm environmental conditions where the device will beplaced. Do not use the devise in the following environmental
conditions:① Water or oil spatters, or high condensation environment.
② Direct sunlight.
③ Ozone, ultraviolet rays or radiation.
④ Toxic gases such as hydrogen sulfide, sulfuric acid, nitrous
acid, chlorine and its compounds, bromine and itscompounds and ammonium.
⑤ Severe vibration or mechanical shock conditions beyond thelimits prescribed in the catalog or product specification.
The standard vibration condition is applicable to JIS C
5101-4.

Maintenance inspections(1) For industrial use capacitors, make periodic inspections of
the capacitors. Before the inspections, turn off the power
supply of the device and discharge the electricity of the capacitors. Where checking it by a volt-ohm meter, confirm
the polarity beforehand. Do not apply mechanical stress tothe terminals of the capacitors during inspection.
(2) Characteristics to be inspected① Significant damage in appearance: vent opening, electrolyte
leakage, etc.
② Electrical characteristics: Leakage current, capacitance,tanδ and other characteristics prescribed in the catalogs or
product specifications. If finding anything abnormal on thecharacteristics above, check the specifications of the capacitor and take appropriate actions such as replacement.

5

Contingencies

1) A capacitor with more than a certain case size has the pres-sure relief vent functioning to escape abnormal gas pressure increase. If gas expels from a venting capacitor, disconnect the power supply of the device or unplug the power
supply cord. If not disconnecting the power supply, thedevice circuit may be damaged due to the short circuit failure of the capacitor or short-circuited with the liquid that thegas was condensed to. It may cause secondary damages

such as device burnout in the worst case scenario. The gasthat comes out of the open vent is vaporized electrolyte notsmoke.
C.
2) The gas expelled from a venting capacitor is more than 100°
Never expose your face to the capacitor. If your eyes are
exposed to the gas or you inhale it, immediately flush youreyes and/or gargle with water. If the electrolyte comes incontact with the skin, wash with soap and water.

6

Storage

1) Do not store capacitors at high temperature or high humidity.

Store the capacitors indoors at temperatures of 5 to 35°C
and humidifies of less than 75%RH.
In principle, conductive polymer hybrid aluminum electrolytic
capacitors should be used within 2 years after production.
2) Keep capacitors packed in the original packaging material wherever possible.
3) Avoid the following storage environmental conditions:① Water spattering, high temperatures, high humidity or condensation environment.
② Oil spattering or oil mist ﬁlled.
③ Salt water spattering or salt filled.
④ Acidic toxic gases such as hydrogen sulfide, sulfuric acid, nitrous acid, chlorine, bromine and methyl bromide filled.
⑤ Alkaline toxic gases such as ammonium filled.
⑥ Acid or alkaline solutions spattering.
⑦ Direct sunlight, ozone, ultraviolet rays or radiation.
⑧ Extreme vibration or shock loading.
4) JEDEC J-STD-020 is not applicable.

7

Capacitor disposal

Please consult with a local organization for the proper disposalof industrial waste. For incinerating capacitors, apply a hightemperature incineration (over 800°C). Incinerating them attemperatures lower than that may produce toxic gases such as
chlorine. To prevent capacitors from explosion, punch holes inor sufficiently crush the can cases of the capacitors, thenincinerate.
