Cautions for Using Conductive Polymer Hybrid Aluminum Electrolytic Capacitors

Please be sure to read this specification before using this product.
Before placing an order, please inquire about the Specification to check details.

Cautions for Usage

1. Conductive Polymer Hybrid Aluminum Electrolytic Capacitors are polarized.
• Using a capacitor with reversed polarity causes
abnormal current flow, resulting in a short circuit.
• Cannot use for the circuit to which the polarity
reverses by ripple voltage.
2. Prohibited Circuits• Since leakage current problem may arise, capacitors
cannot be used in the following circuits.
①Coupling circuits②Circuits greatly affected by leakage current
3. Use capacitors within the rated voltage.
• The application of voltages exceeding the rated
voltage can significantly increase leakage current,
resulting in a short failure. Please do not apply avoltage exceeding the rated voltage.
4. Be careful of excessive rush current.
• Using capacitors in the circuit where excessive
rush current passes may cause characteristic
deterioration or a short. When the rush current
exceeds 10 A, we recommend use of protection
circuits to ensure high reliability.
5. Use the allowable ripple voltage and the rated
ripple current below the specified values.
• When superimposing a ripple voltage on a DC bias
voltage, exercise care that the peak voltage value
does not exceed the rated voltage and does notreverse the polarity.
• The rated ripple current shall be below the specifiedvalue.
6. Changes in characteristics due to operating
temperature• The characteristics of conductive polymer hybrid
aluminum electrolytic capacitors vary by temperature as follows. These variations are temporary andrecover when the temperature goes back (except forthe case of characteristic deterioration because ofhigh temperatures over a long time).
Note that using capacitors over the upper categorytemperature increases leakage current, resulting ina short and destruction.
Be careful of the capacitor temperature considering
not only the ambient temperature where theequipment is placed and the temperature inside theequipment but also radiation heat from the heating
element inside the equipment, and self-heat
generation by ripple current.

NOTE : ‌Design, Specifications are subject to change without notice.
It is recommended that you shall obtain technical specifications
from ELNA to ensure that the component is suitable for your use.

①Capacitance expressed in the value at 20°C, 120
Hz increases with increased temperature anddecreases with decreasing temperature.
②Tangent of loss angle (tanδ) expressed in thevalue at 20°C, 120 Hz is temperature-independent.
③Equivalent series resistance (ESR) expressed inthe value at 20°C, 100 kHz is temperature
independent.
④Leakage current increases with increased
temperature and decreases with decreasing
temperature.
7. Changes in characteristics due to frequency• The characteristics of conductive polymer hybrid
aluminum electrolytic capacitors, solid conductive
polymer aluminum electrolytic capacitors vary byoperating frequency as follows.
①Capacitance expressed in the value at 20°C, 120
Hz decreases with increased frequency.
②Tangent of loss angle (tanδ) expressed in thevalue at 20°C, 120 Hz increases with increased
frequency.
③Equivalent series resistance (ESR) expressed in
the value at 20°C, 100 kHz increases withdecreasing frequency.

exposed to water, saltwater spray, oil spill orcondensation.
• Do not use capacitors in an environment filled with
toxic gas such as hydrogen sulfide, sulfurous acid,nitrous acid, chlorine, ammonia, etc.
• Do not use capacitors in a place exposed to ozone,ultraviolet rays, or radiation.
9 . Fumigation Process• Before transportation of electronic equipment tooverseas, fumigation process may be subjected towooden packing material with a halogen(compound) gas such as methyl bromide. Exercise
care that this halogen gas may corrode capacitors.
Also, be careful of epidemic preventive agent as
corrosive component such as halogen may becontained.
10. The case of Conductive Polymer Hybrid Aluminum Electrolytic Capacitors and the cathodeterminal are not insulated.
• The case and the cathode terminal are not insulated
as being connected through inconstant resistance.

11. Double-sided PCB’s• When using capacitors on a double-sided PCB,
exercise care that the wiring pattern does not touch
the area where the capacitors are mounted. Failure
to do so may cause a short to occur to the PCB
depending on the mounting conditions.
12. Regarding Connection of Conductive Polymer
Hybrid Aluminum Electrolytic Capacitors• When connecting more than one capacitor inparallel, consider the current balance.
13. Use at a high altitude• The use of capacitors at high altitudes such as on anairplane causes a large difference between theinternal pressure of the capacitors and the atmosphericpressure. However, there is no problem in use underatmospheric pressure up to about an altitude of
10,000 meters.
If the condition is severe like space, please contact us.
14. Other Notes• Do not use capacitors on a circuit where rapid
charge and discharge are repeated.
• Electrical characteristics of capacitors vary byvariations in temperature and frequency. Pleaseconsider these variations when designing a circuit.
Cautions for Mounting

1. Cautions for Mounting• Do not reuse capacitors that have been assembled
in a set and energized. Capacitors cannot be reused
except for those which have been measured onelectrical performance during periodic inspection.
• Before mounting, confirm the capacitor ratings(rated capacitance and rated voltage).
• Capacitors may generate transient recovery voltage.
In this case, discharge through a resistor of about
1 kΩ.
• Before mounting, confirm the polarity of capacitor.
• Do not drop capacitors onto a floor nor use them.
• Do not mount deformed capacitors.
• Do not mount heating parts around capacitors andon the back of the PCB under or back of capacitors).
2. Do not apply excessive pressure to the capaci-tor or its terminals• Be careful of the shock force that can be produced
by absorbers, product checkers, and centering on
automatic inserters and installers.

NOTE : ‌Design, Specifications are subject to change without notice.
It is recommended that you shall obtain technical specifications
from ELNA to ensure that the component is suitable for your use.

3. Soldering• SMD type have no capability to with stand such dipor wave soldering immersing components into asolder bath.
• Reflow soldering
Reflow the capacitors within recommended reflow
soldering conditions. Verify there is no temperaturestress to the capacitors because the following
differences might degrade capacitors electricallyand mechanically.
• Caution for reflow soldering
1)Location of components : Temperature increases
at the edge of PC board more than the center.
2)Population of PC board : The lower the component population is, the more temperature rises.
3)Material of PC board : A ceramic-made board
needs more heat than a glass epoxy-madeboard. The heat increase may cause damage tothe capacitors.
4)Thickness of PC board : A thicker board needs
more heat than a thinner board. The heat maydamage the capacitors.
5)Size of PC board : A larger board needs moreheat than a smaller board. The heat may damage
the capacitors.
6)Solder paste thickness
If thin solder paste is to be used comparedrecommend solder paste thickness, please
consult with us.
7)Location of infrared ray lamps : IR reflow as well
as hot plate reflow heats only on the reverse sideof the PC board to lessen heat stress to thecapacitors.
8)Case leakage current will increase (about severalmA at the maximum) after the reflow process, theleakage current which rose gradually decreases
when voltage is applied.
9)Please consult us about vapor phase soldering(VPS).
• Rework of soldering
Use a soldering iron for rework. Do not exceed aniron tip temperature of 400±5℃ and an exposure
time of 3+10 seconds.
4. Handling after Soldering• Do not pick up or move PCB by holding a capacitor.
• Do not bump capacitors against objects. Whenstacking PCB’s, make sure that capacitors do nottouch the PCB’s or other components.
• Do not subject capacitors to excessive stress.

residues and contaminants from between the PCB
and the sealing section of capacitors.
• Dry the cleaning solution before using the adhesiveor coating.
• Do not cover up all the sealing sections (terminalside) of capacitors with the adhesive or coating.
• Heat curing conditions of fixative and coating.
• Please contact us when using a capacitor moldedwith resin.
6. Other Cautions
1. Do not directly touch the terminals of Conductive Polymer Hybrid Aluminum Electrolytic
Capacitors.
Failure to do so can cause electric shock or burns.
Before use, allow capacitors to discharge through a
1kΩ resistor (with a sufficient margin to the heatgeneration capacity) as needed.
2. Do not short-circuit between the terminals of theConductive Polymer Hybrid Aluminum Electrolytic Capacitors. Do not subject capacitors toconductive solutions such as acid and alkaline
water solutions.
3. Periodic inspection should be performed on thecapacitors for the industrial equipment application.
Check the following checkpoints.
• Visual inspection to check for significant defects.
• Electrical performance: leakage current, rated
capacitance, tangent of loss angle, ESR, and items
specified in the catalog or the specification.

NOTE : ‌Design, Specifications are subject to change without notice.
It is recommended that you shall obtain technical specifications
from ELNA to ensure that the component is suitable for your use.

4. Be careful of the following cases of emergency.
• In case of a short during use of capacitors in sets,
producing gas, turn off the main power of the set or
unplug the power cord from the outlet.
• In case of a short, producing gas, it may take a few
seconds to a few minutes depending on theconditions. Therefore, ensure that the protective circuitof the power supply works during this time.
• If the gas gets in your eyes, rinse them immediately.
Gargle if the gas is inhaled.
• Do not lick the electrolyte of capacitors. When theelectrolyte gets on your skin, wash it off with soap
immediately.
5. Storage Conditions.
• Do not store at high temperature and high humidity.
Store at a temperature of 5 to 35°C and a relative
humidity of less than 75%, keeping free from direct
sunlight.
• There may have increased leakage current whenunused or stored for a long time after mounted onequipment. This phenomenon often occurs at highambient temperatures; however, leakage current will
decrease through voltage treatment. If leakage
current still increases after a lapse of more than one
year at ambient temperature (shorter time at hightemperatures), treat with voltage as needed. In
design of equipment, consider the effect of increase
in initial current, and install protective circuits asneeded.
Please check that recommended voltage treatment
conditions are provided for each series.
• Do not store capacitors in an environment directlyexposed to water, saltwater spray, oil spill orcondensation.
• Do not store capacitors in an environment filled with
toxic gas such as hydrogen sulfide, sulfurous acid,nitrous acid, chlorine, ammonia, etc.
• Do not store capacitors in a place exposed to ozone,ultraviolet rays, or radiation.
6. Please take the following actions when disposing of Conductive Polymer Hybrid Aluminum
Electrolytic Capacitors.
• Entrust to specialists of industrial waste treatment forincineration.
