Product Safety Guidelines
Never touch a live capacitor terminals or wires.
Never exceed the rated voltage. Surge voltage is the maximum overvoltage including DC, peak AC and transients to which capacitors may be subjected for short period of time. This overvoltage causes a large amount of current to flow into a capacitor which generates internal gas, raises the vapor pressure and causes abnormal internal pressure. The pressure will cause a safety vent, if present, to rupture or damage the rubber seal causing electrolyte leakage. In extreme cases, the capacitor can explode or catch on fire. *The surge voltage (Us), which exceeds the rated voltage (Ur) of capacitors has been defined in the Japanese Industrial Standard (JIS) as the following…
When Ur ≤200 volts: Us = Ur X 1.25
When Ur >200 volts: Us = Ur + 50 volts
Never short the terminals, as this can create a heavy spark which can damage the terminals.
Use resistance to discharge the capacitor, then short direct by wire before handling the capacitor.
Capacitors with metal containers should be earthed.
DC electrolytic capacitors should always be connected with the correct polarity. Incorrect polarity can cause irreversible damage and can cause the capacitor to explode.
Aluminum electrolytic capacitors that are damaged could have electrolyte leakage which should not come into contact with the eyes or skin. If electrolyte does come in contact with the skin, wash the affected areas immediately with running water. If the eyes are affected, rinse them for 10 minutes with copious amounts of water. If symptoms persist, seek medical attention. Avoid inhaling any vapor or mist that comes from electrolyte. Use in well-ventilated area and use care not to get electrolyte on clothing.
Using capacitors beyond their maximum specified limits can reduce performance and cause catastrophic failure such as short circuit, open circuit, electrolyte leakage, explosion or fire. Use capacitors within the limits of the operating temperature and permissible ripple current specified in the product literature.
Do not use capacitors in devices exposed to extreme environments. Exposing capacitors to inappropriate environments may cause damage and deterioration that affect the assured lifetime in the product literature.
- The following environmental conditions should be avoided.
Water, saltwater or high condensation
Oil or oil spatters
Toxic gas such as nitric acid, hydrogen sulfide, sulfuric acid, chlorine or ammonium
Direct sunlight, ultraviolet rays, ozone or radiation
Extreme vibration, mechanical shock or stress exceeding specified limits in the product literature
