GENERAL INFORMATION FOR APPLICATION
The following precautions must be observed when using electrolytic capacitors.
1. Circuit Design
1) Please make sure that the environmental and mounting conditions to which the capacitor to be
exposed are within the conditions specified in this catalogue.
2) Operating temperature and applied ripple must be within the specifications.
3) Appropriate capacitors, which comply with the life requirement of the products, should be selected
when designing the circuit.
4) Aluminum electrolytic capacitors are polarized. Do not apply reserve voltage or AC voltage. Please
use non-polarized capacitors for a circuit that can possibly see reserved polarity.
Note: Non-polarizes capacitors cannot be used for AC voltage application.
5) Do not use aluminum electrolytic capacitors in a circuit that requires rapid and very frequent charge
or discharge. In this type of circuit, it is necessary to use special design capacitors with extended life
characteristics.
6) Do not apply excess voltage.
M Pleased pay attention so that the peak voltage, which is DC voltage overlapped by ripple current,
should not exceed the rated voltage.
N In the case where more than two aluminum electrolytic capacitors are used in series, please
make sure that applied voltage should be lower than rated voltage should be applied to each
capacitor equally using a balancing resistor in parallel with the capacitor.
7) Outer sleeved of the capacitor is not guarantee as an electrical insulator. Do not use standard sleeve
on a capacitor in applications that require electrical insulation. When the application requires special
insulation, please contact our sales office for details.
8) Capacitors must not be used under following conditions:
M (a) Capacitors must not be exposed to water (including condensation), brine or oil.
(b) Ambient conditions that include toxic gases such as hydrogen sulfide, sulfurous acid, nitrous
acid, chlorine, ammonium, etc.
(c) Ambient conditions that expose the capacitor to ozone, ultraviolet ray and radiation.
N Severe vibration and physical shock conditions that exceed our specification.
Vibration test condition:
Vibration frequency range: 10~55~10Hz
Sweet rate
: 10~55~10Hz per minute
Sweet method
: logarithmic
Amplitude or acceleration: 1.5 (max. acceleration is 10G)
Direction of vibration
: X, Y, Z direction
Testing time
: 2 hours per each direction
Shock is not applicable normally.
If a particular condition is required, please contact our sales office.
DB LECTRO Inc. 3755 Place Java, Suite 140, Brossard, Québec, J4Y 0E4, Canada - T: 1-450-444-1424 / F: 1-450-444-4714 / www.dblectro.com
9) When designing a circuit board, please pay attention to the following:
M Make the pad spacing on the PC board matching with the lead space of the capacitor.
N There should not be any circuit pattern or circuit wire above the capacitor safety vent.
10) The main chemical solution of the electrolyte and the separator paper in the capacitor are
combustible. The electrolyte is conductive. When it comes in contact with the PC board, there is a
possibility of pattern or short circuit between the circuit pattern, which could result in smoking or fire.
Do not locate any circuit pattern beneath the capacitor end seal.
11) Do not design a circuit board so that heat generating components are placed near an aluminum
electrolytic capacitor or reserve side of PC board (under the capacitor).
12) Please refer to the pad size layout recommendations in our catalogue when designing in surface
mount capacitors.
13) Electrical characteristics may vary depending on changes in temperature and frequency. Please
consider the variation when you design circuits.
14) When you install more than 2 capacitors in parallel, consider the balance of current following in to the
capacitor.
2. Mounting
1) Once a capacitor has been assembled in the set and power applied, do not attempt to re-use the
capacitor in other circuits or application.
2) Electric potential between positive and negative terminal may exist as a result of returned
electromotive force, so please discharge the capacitor using 1K: resistor.
3) Leakage current of the parts that have stored for long period may increase. When leakage current
4)
5)
6)
7)
8)
has increased, please perform a voltage treatment using a 1K: resistor.
Please confirm rating and polarity before installing capacitor on the PC board.
Be careful not to deform the capacitor during installation.
Please confirm that the lead spacing of the capacitor matches the pad spacing of the PC board prior
to installation.
Please pay attention to the mechanical shock to the capacitor by suction nozzle of the automatic
insertion machine or automatic mounted, or by product checker, or by centering mechanism.
Reflow soldering: Please see "Lead Free Reflow Soldering Condition" for chip type aluminum
electrolytic capacitors (page 8).
9) Do not tilt, lay down or twist the capacitor body after the capacitors are soldered to the PC board.
10) Do not carry the PC board by grasping the soldered capacitor.
11) Please do not allow anytime to touch the capacitor after soldering. If PC board are stored in stack,
please make sure PC board or the other components do not touch the capacitor. The capacitor shall
not be effected by any radiated heat from the soldered PC board or other components after
soldering.
12) Cleaning
M Do not clean capacitors with halogenated cleaning agent. However, if it is necessary to clean with
halogenated cleaning agent, please contact our sales office.
N Recommended cleaning method:
Applicable
: Any type, any ratings
Cleaning agents : Pine Alpha ST-100S, cleaning through 750H/750L/710M, Sanelek B-12, Aqua
Cleaner 210SEP, Techno Care FRW14~17, Isopropyl Alcohol.
DB LECTRO Inc. 3755 Place Java, Suite 140, Brossard, Québec, J4Y 0E4, Canada - T: 1-450-444-1424 / F: 1-450-444-4714 / www.dblectro.com
Cleaning condition: Total cleaning time shall be within 5 minutes by immersion, ultrasonic or other
method. Temperature of the cleaning agent shall be 60qC or lower. After
cleaning, capacitors should be dried using hot air for minimum of 10 minutes
along with the PC board. Hot air temperature should be below the maximum
operating temperature of the capacitor. Insufficient dry after water rinse may
cause appearance problems, sleeve shirk, bottom- plate bulge and such.
e Avoid using ozone destructive substance for cleaning agents to concern about global
environment. Please consult us regarding other cleaning agents or cleaning methods.
3. In The Equipment
1) Do not directly touch terminal by hand.
2) Do not short between terminal by conductor, nor spill conductible liquid such as alkaline or acidic
solution on or near the capacitor.
3) Please make sure that the ambient conditions where the set is installed will be free from spilling water
or oil, direct sunlight, ultraviolet rays, radiation, poisonous gases, vibration or mechanical shock.
4. Maintenance and Inspection
Please periodically inspect the aluminum capacitors that are installed in industrial equipment. The
following Items should be checked:
Appearance: Remarkable abnormality such as vent operation, leaking electrolyte etc.
Electrical characteristic: Capacitance, dielectric loss tangent, leakage current etc., which are specified
in this catalogue.
5. In an Emergency
1) If you see smoke due to operation of safety vent, turn off the main switch or pull out the plug from the
outlet.
2) Do not draw your face to the safety vent since gas over 100qC will be emitted when the safety vent
operates. If the gas has entered your eyes, please flush your eyes immediately in pure water. If you
breathed the gas immediately wash out your mouth and throat with water. Do not ingest electrolyte. If
your skin is exposed to electrolyte, please wash it away using soap and water.
6. Storage
1) Do not keep capacitor in high temperature and high humidity.
Storage conditions should be:
Temperature : +5qC ~ +35qC
Humidity
: Lower than 75%
Place
: Indoor
2) Avoid ambient conditions where capacitors can be covered with water, brine or oil.
3) Avoid ambient conditions where capacitors are exposed to poisonous gases such as hydrogen sulfide,
sulfurous acid, nitrous acid, chlorine, ammonium etc.
4) Do not keep capacitor in conditions that expose the capacitor to ozone, ultraviolet ray or radiation.
7. Disposal
Please dispose capacitors in either of the following ways:
1) Incinerate capacitors after crushing parts or making a hole on the capacitor body.
2) Bury capacitors in the ground. Please have a disposal specialist do it.

LIFE OF ALUMINUM ELECTROLYTIC CAPACITORS
The life of aluminum electrolytic capacitors is mainly dependent on environmental conditions (e.g.
ambient temperature, humidity etc.) and electrical factors (e.g. operating temperature, ripple current
etc.) Generally, the wear-out mechanism of aluminum electrolytic capacitors is based on evaporation
of electrolyte through the rubber seal. Consequently, the factor of temperature (ambient temperature
and internal heating due to ripple current) is the most critical to electrolytic capacitors life. The effect of
voltage on capacitor life is negligible, especially for low voltage electrolytic capacitors. The lifetime of
aluminum electrolytic capacitors can be expressed as following equations:
Le = Lo x Kt x Kr
-------- (1)
Where:
Le = Expected life at operating temperature Te (h)
Lo = Specified life at temperature operating temperature To (h)
Kt = Ambient temperature acceleration term
Kr = Ripple current acceleration term
(To-Te)/10
Kt = Lo x A
-------- (2)
Where:
To = Maximum rated operating temperature (qC)
Te = Actual ambient temperature (qC)
A = Acceleration coefficient (for the range from 35qC to the maximum operating temperature,
A|2)
Kr = 2 (-'T/5)
-------- (3)
Where:
'T = An increase in core temperature by internal heating due to ripple current
('T = core temperature – ambient temperature)
'T can be estimated as follows:
'T = (I2 x R)/(E x S) -------- (4)
Where:
I = Ripple current of the capacitor (A rms)
R = Equivalent series resistance of the capacitor (:)
E = Heat radiation coefficient of the aluminum can (W/qC x cm2)
S = Surface area of the capacitor (cm2)
