Aluminum Electrolytic Capacitors
General Information For Application
The following cautions must be observed when using electrolytic capacitors
1. Polarity:
DC electrolytic capacitors are polarized. If used in reverse polarity, the circuit life may be damaged.
For usage on circuits whose polarity is occasionally reversed or whose polarity is unknown, use non-polar
capacitors.
2. Operating Voltage:
Do not apply a voltage exceeding the capacitor's rated voltage. Otherwise, the capacitors may be damaged
as leakage current increases.
3. Ripple Current:
The ripple current on the capacitors should be at or below permissible level. Do not allow the current to
pass the capacitors in excess of the specified ripple current.
4. Operating Temperature:
The capacitors should not be used in other than the guaranteed temperature range. Usage at room temperature
will ensure long life.
5. Leakage Current:
The leakage current shall be within specified levels. When capacitors are at a lower voltage, the actual leakage
current will be reduced proportionately.
6. Safety Vent:
Case diameters of 6.3mm and larger for Radial types are designed with case venting, and case diameters
of 8mm and larger for Axial types are designed with safety vent on rubber bung.
7. Soldering:
(A) Be careful of temperature and time when soldering. Dip of flow soldering of the capacitors should be
limited to less than 260
