Components

USAGE CONDITIONS
The following cautions must be observed when using electrolytic capacitors.

1. DC Electrolytic Capacitors have the polarity.
    Make sure of the polarity, Application of the reversed voltage may cause a short circuit or
    damage to the capacitors when the polarity is not determined or unknown. Note that DC
    electrolytic capacitors cannot be for used for AC application.

2. Capacitors are not suitable operating with sudden charge
    and discharge are frequently repeated.
    In the circuit subjected to rapid charge cycles, capacitors may be damaged. Be sure
    and use special capacitors in these applications.

3. Be sure not to apply a voltage exceeding the rated voltage.
    If a voltage exceeding the rated voltage is applied the leakage current will increase
    which may damage the capacitor. For a short period however the capacitor
    withstands up to the surge voltage.

4. Be sure not to flow excessive ripple current through the capacitor.
    The flow of ripple current over the permissible ripple current will cause heat of the
    capacitor, which may decrease the capacitance and damage the capacitor. Use
    capacitors designed for high ripple current application.

5. Capacitors should be stored in cold and dry placed which have
     been stored for a long period.
    The capacitors after long storage tends to have high leakage current which may
    damage the capacitor by the excessive heat because of high leakage current
    flow. Use it after voltage treatment(aging).

6. Be sure of the temperature range.
    The characteristics of capacitors change with the operating temperature. This change
     is temporary and Restorable with in the specified temperature range. Be sure not to
     use capacitors below or over the recommended temperature range.

7. Be sure not to apply excessive force to the terminals and leads.
The excessive strong force applied to the terminals and lead wires may break them
and loosen the connections of the internal elements.

8. Capacitance decreases at higher frequencies.
    The capacitance value is measured at 120Hz. The capacitance decreases as the
    applied frequency becomes higher whereas increases as the ambient temperature
    becomes higher.

9. Tangent of loss angle increases at higher frequencies.
The tangent of loss angle(tand ) increase as the applied frequency becomes higher
whereas the ambient temperature becomes higher.

10. Be careful of temperature and time when soldering.
      Dipping must be performed at the soldering temperature or less than 260º c for
      less than 10 seconds otherwise the capacitors may be damaged , and the sleeve
      of the capacitors may deform and crack from the extremely high temperature.

11. Be cautions of cleaning the circuit board after soldering.
      Cleaning protection for sleeve marking and sealing materials on capacitors body will
      not be damaged, which should never be washed or cleaned by halogens agents or
      solvents such as trichloroethene, Xyiene or acetone etc.

12. The specification of products are according to characteristic (w),
established by JIS-C5141.
