CP-CAP
PRECAUTIOS AD GUIDELIE
CP-CAP is a solid aluminum capacitor with conductive polymer electrolyte. Please read the following points in
order to take the most out of your CP-CAP capacitor.
S
FOR CONDUCTIVE POLYMER CAPACITORS
Designing device circuits
1. Circuits where CP-CAP capacitors are prohibited to used
The leakage current of conductive polymer solid aluminum capacitors may vary depending on thermal
stresses. Please don’t use solid capacitors in the following types of circuits:
a) High-impedance circuits that are to sustain voltages.
b) Coupling circuits
c) Time constant circuits
In addition to the leakage current fluctuation, capacitance may also fluctuate depending on operational
temperature and humidity. The fluctuation of the capacitance may cause problem if it is used as a time
constant capacitor, which is extremely sensitive to the fluctuation of the capacitance. Do not use it as a
time constant capacitance.
d) Other circuits that are significantly affected by leakage current. If you want to use 2 or more CP-CAPs
in a series connection, please contact us before use.
2. Polarity
The CP-CAP is a polarized solid aluminum electrolytic capacitor. Do not apply either reverse voltages or AC
voltages to the polarized capacitors, using reverse polarity may cause a short circuit. Refer to the catalog,
product specifications or capacitor body to confirm the polarity prior to use.
3. Applied voltage
Do not apply DC voltages exceeding the full rated voltage. The peak voltage of superimposed AC voltages
(ripple voltages) on DC voltages must not exceed the full rated voltage. While there are specifications for
surge voltages exceeding the rated voltage, usage conditions apply, and continued operation for extended
periods of time under such conditions cannot be guaranteed. Use the within 20% of the rated voltage for
applications which may cause the reverse voltage during the transient phenomena when the power is turned
off or the source is switched.
4. Ripple current
Do not apply currents in excess of the rated ripple current. The superimposition of a large ripple current
increases the rate of heating within the capacitor. This may reduce the service life of the capacitor or damage
the capacitor.
5. Operating temperature
Do not use the CP-CAP capacitor at high temperatures (temperatures exceeding the maximum temperature
for the capacitor category) Use of the capacitor outside of the maximum temperature for the capacitor
category may decrease the service life of the capacitor.
6. Sudden charge and discharge
Do not use the CP-CAP capacitor in circuits where the capacitor is repetitively charged and discharged
rapidly. Repetitively charging and discharging the capacitor rapidly may reduce the capacitance or may cause
damage due to internal heating. Use of a protective circuit to ensure reliability is recommended when rush
currents exceed 10A or the rush current is over 10 times of allowable ripple current of CP-CAP .
A protection resistor(1 kΩ) must be inserted to the circuit during the charge and discharge when measuring
the leakage current.
7. Failures and life-span
11
Page 14
CapXon
CP-CAP
PRECAUTIOS AD GUIDELIE
The CP-CAP failure rate in use is based on the failure rate level in the specification requirements. Upper
category temperature and category voltage adhere to JIS C 5003 Standard. The confidence level is 60% and
the failure rate is 0.5%/1,000 hours (applied rated voltage at category temperature).
The failure modes mainly have 2 types as follows.
(1) Contingency failure
The contingency failure mainly has short circuit. The phenomenon of after short is on following.
(i) In the event a short circuit causes the current to become relatively small(less than approximately 1A for
φ10,less than approximately 0.5A forφ8 and less than approximately 0.2A for smaller thanφ6.3 ),the
CP-CAP itself will generate a little heat, but its appearance will not be affected even when electricity is
supplied continuously. However, if the short circuit current value exceeds the mentioned values above, the
temperature inside the CP-CAP will increase, the internal pressure is raised, rubber sealing is turned over,
and odorous gas is released. In this case, keep your face and hands away from the area.
(ii)The electrolyte, electrolytic paper, sealing rubber, and plastic spacer used in the CP-CAP are all
combustible. If an extremely large electric current flows through the capacitor after shorting, the shorted part
may spark, and in a worst case scenario, may ignite. Ensure safety by fully considering the design issues
described below when using this capacitor in equipment where safety is a priority.
• Increase safety by using in conjunction with a protective circuit or protective equipment.
• Install measures such as redundant circuits so that the failure of a part of the equipment will not cause
unstable operation.
(2) performance characteristic and failure(life-span)
CP-CAP characteristics can possibly change(capacitance reduction and ESR increase) within the specified
range in specifications when it is used in the condition of rated voltage, electric and mechanical performance.
When life span exceeded the specified guarantee time of endurance and damp heat, electric aharacteristic
might change and cause electrolyte insulation. This is called open circuit mode. It is recommended to use the
capacitor at a lower temperature than the maximum temperature for the capacitor category.
8. Circuit design
Verify the following before designing the circuit:
a) The electrical characteristics of the capacitor will vary depending on differences in temperature and
frequency. Only design your after verifying the scope of these factors.
b) When connecting two or more capacitors in parallel, ensure that the design takes current balancing into
account.
c) When two or more capacitors are connected in series, variability in applied voltage may cause over-voltage
conditions. Contact CapXon before using capacitors connected in series.
9. Capacitor usage environment
Do not use/expose capacitors to the following conditions.
a) Oil, water, salty water, take care to avoid storage in damp locations.
b) Direct sunlight
c) Toxic gases such as hydrogen, sulfide, sulfurous acids, nitrous acids, chlorine and chlorine compounds,
bromine and bromine compounds, ammonia, etc.
d) Ozone, ultraviolet rays and radiation.
e) Severe vibration or mechanical shock conditions beyond the limits advised in the product specification
section of the catalog.

10. Capacitor mounting
a) For the surface mount capacitor, design the copper pads on the PC board in accordance with the catalog or
the product specification
b) For radial capacitors, design the terminal holes on the PC board to fi t the terminal pitch of the capacitor.
11. Leakage current
Heat pressure from soldering and mechanical stress from transportation may cause the leakage current to
become large. In such a case, leakage current will gradually decrease by applying voltage less than or equal to
the rated voltage at a temperature within the upper category temperature. In close conditions to the upper
category temperature, the nearer the applied voltage is to the rated voltage, the faster the leakage current
recovery speed is.
S
FOR CONDUCTIVE POLYMER CAPACITORS
Mounting precautions
1. ote
a) For the surface mount capacitor, design the copper pads on the PC board in accordance with the catalog or the
product specification
b) For radial capacitors, design the terminal holes on the PC board to fit the terminal pitch of the capacitor.
c) Mount after checking the capacitance and the rated voltage.
d) Mount after checking the polarity.
e) Do not apply excessive external force to the lead terminal and the CP-CAP itself.
f) Ensure that the soldering conditions meet the specifications recommended by CapXon. Note that the leakage
current may increase due to thermal stresses that occur during soldering, etc. Note that increased leakage
currents gradually decrease when voltage is applied.
2. Soldering using a soldering iron:
a) The soldering conditions (temperature and time) are within the ranges specified in the catalog or product
specifications.
b) The tip of the soldering iron does not come into contact with the capacitor itself.
3. Flow soldering
a) 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.
b) Soldering conditions (preheat, solder temperature and dipping time) should be within the limits prescribed in
the catalog or the product specifications.
In regards to flow soldering, be sure to solder within the following conditions.
Temperature
Preheating
Soldering conditions 260+5℃ or less 10+1 sec. or less Twice or less
c) Do not apply flux to any part of capacitors other than their terminals.
d) Make sure the capacitors do not come into contact with any other components while soldering.
4. Reflow soldering
a) Soldering conditions (preheat, solder temperature and soldering time) should be within the limits prescribed
in the catalogs or the product specification.

The leakage current value may increase(from a few μA to a few mA) even within the above conditions. When
the CP-CAP is used in a DC circuit, the leakage current will decrease gradually through self-recovery after
voltage is applied. If your reflow profile deviates from the above conditions for mounting the CP-CAP, please
consult with CapXon.
5. Handling after soldering
Do not apply any mechanical stress to the capacitor after soldering onto the PC board.
a) Do not lean or twist the body of the capacitor after soldering the capacitors onto the PC board
b) Do not use the capacitors for lifting or carrying the assembly board.
c) Do not hit or poke the capacitor after soldering to PC board. When stacking the assembly board, be careful
that other components do not touch the aluminum electrolytic capacitors.
d) Do not drop the assembled board.
6. Washing the PC boards
a) Do not wash capacitors by using the following cleaning agents. Solvent resistant capacitors are only suitable
for washing using the cleaning conditions prescribed in the catalog or the product specification. In particular,
ultrasonic cleaning will accelerate damage to capacitors.

• Halogenated solvents; cause capacitors to fail due to corrosion.
Alkali system solvents; corrode (dissolve) an aluminum case.
• Petroleum system solvents; cause the rubber seal material to deteriorate.
• Xylene; causes the rubber seal material to deteriorate.
• Acetone; erases the markings.
b) Verify the following points when washing capacitors.
• Monitor conductivity, pH, specific gravity and the water content of cleaning agents. Contamination adversely
affects these characteristics.
• Be sure not to expose the capacitors under solvent rich conditions or keep capacitors inside a closed container.
In addition, please dry the solvent sufficiently on the PC board and the capacitor with an air knife
(temperature should be less than the maximum rated category temperature of the capacitor) for 10 minutes.
Aluminum electrolytic capacitors can be characteristically and catastrophically damaged by halogen ions,
particularly by chlorine ions, though the degree of the damage mainly depends upon the characteristics of the
electrolyte and rubber seal material. When halogen ions come into contact with the capacitors, the foil
corrodes when a voltage is applied. This corrosion causes an extremely high leakage current which results
venting and an open circuit.

FOR CONDUCTIVE POLYMER CAPACITORS
Storage
The following conditions for storage are recommend.
a) Store capacitors in a cool, dry place. Store at a temperature between 5 and 35℃, with a humidity of 75% or less.
SMD products are sealed in a special laminated aluminum bag. Use all capacitors once the bag is opened.
Return unused capacitors to the bag, and seal it with a zipper. Be sure to follow our recommendations for
reflow soldering.
b) Store the capacitors in a location free from direct contact with water, salt water, and oil.
c) Store in a location where the capacitor is not exposed to toxic gas, such as hydrogen sulfide, sulfurous acid,
nitrous acid, chlorine or chlorine compounds, bromine or other halogen gases, methyl bromide or other halogen
compounds, ammonia, or similar.
d) Store in a location where the capacitor is not exposed to ozone, ultraviolet radiation, or other radiation.
e) It is recommended to store capacitors in their original packaging wherever possible.
