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.

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

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)
