When using aluminum electrolytic capacitors,pay strict attention to the following:
1. Electrolytic capacitors for DC application require polarization.
Confirm the polarity.If used in reversed polarity,the circuit life may be shortened or the capacitor may be damaged.For
use on circuits whose polarity is occasionally reversed,or whose polarity is unknown,use bi-polarized capacitors (BP-
series).Also,note that the electrolytic capacitor cannot be used for AC application.
2. Do not apply a voltage exceeding the capacitor`s voltage rating.
If a voltage execeeding the capacitor`s voltage rating is applied,the capacitor may be damaged as leakage current inc-
reases. When using the capacitor with AC voltage superimposed on DC voltage,care must be exercised that the peak
value of AC voltage does not exceed the rated voltage.
3. Do not allow excessive ripple current to pass.
Use the electrolytic capacitor at current values within the permissible ripple range.If the ripple current exceeds the sp-
ecified value,request capacitors for high ripple current applications.
4. Ascertain the operating temperature range.
Use the electrolytic capacitors according to the specified operating temperature range.Usage at room temperature will
ensure longer life.
5. The electrolytic capacitor is not suitable for circuits in which charge and discharge are frequently repeated.
If used in circuits in which charge and discharge are frequently repeated,the capacitance value may drop,or the capaci-
tor may be damaged.Please consult our engineering department for assistance in these applications.
6. Apply voltage treatment to the electrolytic capacitor which has been allowed to stand for a long time.
If the electrolytic capacitor is allowed to stand for a long time,its withstand voltage is liable to drop,resulting in increas-
ed leakage current.If the rated voltage is applied to such a product,a large leakage current occurs and this generates
internal heat,which damaged the capacitor.If the electrolytic capacitor is allowed to stand for a long time,therefore,use
it after giving voltage treatment (Note 1).(However,no voltage treatment is required if the electrolytic capacitor is allow-
ed to stand for less than 2 or 3 years at normal temperature.)
7. Be careful of temperature and time when soldering.
When soldering a printed circuit board with various,components,care must be taken that the soldering temperature is
not too high and that the dipping time is not too long.Otherwise,there will be adverse effects on the electrical charact-
eristics and insulation sleeve of electrolytic capacitors in the case of small-sized electrolytic capacitors,nothing abno-
rmal will occur if dipping is performed at less than 260℃ for less than 10 seconds.
8. Do not place a soldering iron on the body of the capacitor.
The electrolytic capacitor is covered with a vinyl sleeve.If the soldering iron comes in contact with the electrolytic capa-
citor body during wiring,damage to the vinyl sleeve and/or case may result in defective insulation,or improper protecti-
on of the capacitor element.
9. Cleaning circuit boards after soldering.
Some solvents have adverse effects on capacitors.
Please refer to the next page.
10.Do not apply excessive force to the lead wires or terminals.
If excessive force is applied to the lead wires and terminals,they may be broken or their connections with the internal
elements may be affectde.(For strength of terminals,refer to KS C IEC 60384-4(JIS C5101-1,JIS C5101-4)
11.Care should be used in selecting a storage area.
If electrolytic capacitors are exposed to high temperatures caused by such things as direct sunlight,the life of the cap-
acitor may be adversely affected.Storage in a high humidity atmosphere may affect the solderability of lead wires and
terminals.
12.Surge voltage.
The surge voltage rating is the maximum DC over-voltage to which the capacitor may be subjected for short periods n-
ot exceeding approximately 30 seconds at infrequent intervals of not more than six minutes.According to KS C IEC 60384
-4,the test shall be conducted 1000 cycles at room temperature for the capacitors of characteristic KS C IEC 60384-4 or at
the maximum operating temperature for the capacitors of characteristics B and C of KS C IEC 60384-4 with voltage app-
lied through a series resistance of 1000 ohms without discharge.The electrical characteristics of the capacitor after the
test are specified in KS C IEC 60384-4.Unless otherwise specified,the rated surge voltage are as follows:

Note 1 Voltage treatment
… Voltage treatment shall be performed by increasing voltage up to the capacitor`s voltage ra-
ting gradually while lowering the leakage current.In this case,the impressed voltage shall be in the range where t-
he leakage current of the electrolytic capacitor is less than specified value.Meanwhile,the voltage treatment time
may be effectively shortened if the ambient temperature is increased (within the operating temperature range).
Note 2 For methods of testing,
refer to KS C IEC 60384-4，（JIS
C 5101-1，JIS C 5101-4）
