2. Do not apply a voltage exceeding the capacitor's voltage rating .
If a voltage exceeding the capacitor's voltage rating is applied , the
capacitor may be damaged by increased leakage current . When
using the capacitor with AC voltage do not exceed the rated voltage .
3. Do not allow excessive ripple current passing.
Use the electrolytic capacitor at current value within the permissible
ripple range . If the ripple exceeds the specified value , request
capacitors for high ripple current applications .
C (uF) > 1.3 x Current (mA)
I = 1A , => C >1300uF
4. Ascertain the operation temperature range .
Use the electrolytic capacitors according to the specified operation
temperature range . Use at room temperature will ensure a longer
life .
5. The electrolytic capacitor is not suitable for circuits which are
charged and discharged repeatedly .
If used in circuits which are charged and discharged repeatedly , the
capacitance value may drop or the capacitor may be damaged .
Please consult our engineering department for assistance in these
applications .
6. When capacitors have been left unused for long time , use them only
after due voltage treatments . Long storage of capacitors tends to
rise their leakage current levels . In such cases , be sure to provide
the necessary voltage treatment before use .
(5-6h ->10% Ucap, 5-6h-> 20% Ucap, 5-6 hours30% Ucap, ... 5-6h -. 90% Ucap more important -> must be charged with a resistor connected in series)
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 effect on the electrical characteristics
-size electrolytic capacitors , nothing abnormal will be occurred if
and insulation sleeve of electrolytic capacitors . In the case of small
dipping is performed at less than 260℃ for less than 10 seconds
