Precautions (Capacitors)

Precautions for Your Safety

Micro-Energy Division capacitors (XH,CP) contain flammable organic solvents. For your safety, please follow the following prohibitions.

WARNING!

  • Do not charge by higher current or higher voltage than specified. 
    Doing so may generate gas inside the capacitor, resulting in swelling, fire, heat generation or bursting.
  • Do not reverse placement of (+) and (-). 
    SII capacitors have polarity. If the (+) and (-) side of the capacitor is reverse inserted, it may cause short-circuit or over discharge of the capacitor on some equipment and it may induce overheating, explosion or fire.
  • Do not solder directly to the capacitor. (for XH only) 
    If soldering is performed directly to the capacitor, the capacitor will over heat and, consequently cause leakage, explosion or fire due to overheating from internal short-circuit.
  • Keep capacitors out of children’s reach. 
    It is dangerous that children swallow the capacitor. When you design mechanical hardware around the capacitor, please fix the capacitor firmly in order to prevent children from removing it. When you store the capacitors, please keep the capacitors out of children’s reach. If a capacitor is swallowed, consult a physician immediately.
  • Do not heat, disassemble, nor dispose of in fire. 
    Doing so damages the insulation materials and may cause fire, heat generation, leakage or bursting.
  • Do not discharge by force. 
    If the capacitor is discharged by direct connection to an external power supply etc., voltage of the capacitor will decline lower than 0 volt (electrical reversal) and will cause the capacitor case to expand, overheat, leak, explode or burn.
  • In case of leakage or a strange smell, keep away from fire to prevent ignition of any leaked electrolyte.

CAUTION!

  • If leaked liquid gets into the eyes, wash them with clean water and consult a physician immediately. 
  • Do not use nor leave the capacitors in direct sunlight nor in high-temperature areas. 
    It may cause fire, heat generation, leakage or bursting.
  • Do not use new and used capacitors together. Do not use different types of capacitors together. 
    It may cause fire, heat generation, leakage or bursting.
  • If you connect two or more capacitors in series or parallel, please consult us in advance 
    It may cause bursting or fire due to unbalanced load or voltage.
  • Keep capacitors away from direct sunlight, high temperature and humidity. 
    It may cause heat generation or performance deterioration.
