Notes to uses of Aluminum Electrolytic Capacitors
Aluminum electrolytic capacitors ('capacitors') may cause explosion, fire, or other serious hazard if used outside the specified operating conditions. Please familiarize yourself with the instructions below before using these capacitors.
1.Check the operating and installation environment and use the capacitor within the range of the rated performance specified in the catalog or specifications.
2.Maintain operating temperature and ripple current within the specified ranges. Base your choice of capacitors on the maximum load conditions. A capacitor will overheat under excessive current, potentially resulting in short circuit, fire, or other major failure.
3.A capacitor also generates the self heating. Please bear in mind that the capacitor heats up the interior of the equipment, and take appropriate precautions. Operate the unit under normal conditions and check the temperature of the area surrounding the capacitor.
4.The permissible ripple current declines with the rise in ambient temperature (the temperature of the capacitor's surroundings).Consider the permissible ripple current at the maximum predictable ambient temperature.
5.Electric characteristics change as frequencies change. Check frequency changes in order to choose the right capacitor. Special attention needs to be given to the self heating and short life time both low and high frequency, when equivalent series resistance and inductance change.
