From the above, when considering usage of an aluminum electrolytic capacitor in a circuit that will repeat frequent charge and discharge, it is recommended to use capacitors designed to specifically meet conditions of frequent charge/discharge. The following measures are taken to prevent an oxide layer formation on the cathode foil.
In general all aluminium electrolytic capacitors are covered with a PVC sleeve, that is also used for marking. The aluminium can is not insulated from the cathode, so when the internal element needs to be electrically insulated from the can, capacitors specially designed for insulation requirements should be used.
It is important to confirm that the capacitor meets the necessary requirements within the operating temperature range of the equipment, when using an aluminum electrolytic capacitor in a timing circuit. The aluminum electrolytic capacitor is the most commonly used type of capacitor in a smoothing circuit.
For such reasons, aluminum electrolytic capacitors that are used in power supplies are required to have the following features: miniature, light in weight, thin, extended life and high reliability, chip type, and safer. The following discusses factors that will help in proficiently using aluminum electrolytic capacitors.
The capacitance of aluminum electrolytic capacitors changes with temperature and frequency of measurement, so the standard has been set to a frequency of 120Hz and temperature of 20°C. The equivalent circuit of an aluminum electrolytic capacitor is shown below. The equivalent series resistance is also known as "ESR". Capacitance (F)
Aluminum capacitors must be mounted on the "top side" of the P.C. board and only allow the bottom side of the P.C. board to come in contact with the solder. Soldering condition must be confirmed to be within Nichicon specification. e Avoid having flux adhere to any portion of the capacitor except the terminal.

Compensation capacitors are used to counteract reactive current (increased power factor) and are basically either connected in parallel or in series. Compensation capa-citors are not required when using electronic ballasts, whose power factor is generally in the region of 0.95.
Aluminum electrolytic capacitor construction delivers colossal capacitance because etching the foils can increase surface area more than 100 times and the aluminum-oxide dielectric is less than a micrometer thick. Thus the resulting capacitor has very large plate area and the plates are intensely close together.
Aluminum electrolytic capacitors cannot be re-used once the capacitor has assembled in the set and power applied. Aluminum electrolytic capacitors may have electrical potential between positive and negative terminal, please discharge through a 1kΩ resistor before use.
