If exposed to xylene, toluene, etc, and then subjected to high heat, the sleeve may crack. This sleeve is not insulating material.

Regular aluminum electrolytic capacitors has polarity

If the capacitor is cleaned in halogenated solvent for organic removing solder flux solvent, the solvent may penetrate into inside of capacitor, and may generate corrosion.

Do not apply overvoltage continuously. When overvoltage is applied to the capacitor, leakage current increase drastically.

Generally, life time is doubled by decreasing each temperature 10℃

Reverse voltage causes short circuit breakage of the capacitor or leakage of electrolyte. Where the polarity in a circuit sometimes reversed or unknown, a bi-polar capacitor should be used.

Applying too much ripple current to the capacitor causes great heat generation, invites deterioration of properties of causes breakage.

Generally, life time is doubled by decreasing each temperature 10℃

Do not use the capacitor over the max operating temperature. Life time of the capacitor depends on the temperature.

It is recommended to apply D.C. working voltage to the capacitor for 30 minutes through 1kΩ of protective series resistor, if it is stored for more than 6 mouths.

The standard sleeve material is polyvinyl-chloride. If exposed to xylene, toluene, etc, and then subjected to high heat, the sleeve may crack. This sleeve is not insulating material.

It is recommended at least 3mm of space around the vent. If such space is not provided, the vent will not operate completely.
