Aluminum Electrolytic Capacitors
General Information For Application
The following cautions must be observed when using electrolytic capacitors 1. Polarity: DC electrolytic capacitors arepolarized. If used in reverse polarity, the circuit life may be damaged. For usage on circuits whose polarity is occasionally reversed or whose polarity is unknown, use non-polar capacitors. 2. OperatingVoltage: Do not apply a voltage exceeding the capacitor’s rated voltage. Otherwise, the capacitors may be damaged as leakage current increases. 3. Ripple Current: The ripple current on the capacitorsshould be at or below permissible level. Do not allow the current to pass the capacitors in excess of the specified ripple current. 4. Operating Temperature: The capacitors should not be used in other thanthe guaranteed temperature range. Usage at room temperature will ensure long life. 5. Leakage Current: The leakage current shall be within specified levels. When capacitors are at a lower voltage,the actual leakage current will be reduced proportionately. 6. Safety Vent: Case diameters of 6.3mm and larger for Radial types are designed with case venting, and case diameters of 8mm and larger forAxial types are designed with safety vent on rubber bung. 7. Soldering: (A) Be careful of temperature and time when soldering. Dip of flow soldering of the capacitors should be limited to less than260°C and 10 seconds. (B) High levels of humidity will affect the solderability of lead wire and terminals. High temperature will reduce long term operating life. (C) Following defective soldering affectthe internal characteristics, such as increasing leakage current, short circuit, broken or wound of lead wires, and leaking electrolyte. (1.) Parts slant to the board after soldering. (2.) Leads aregreatly bent after soldering. (3.) Lead space on board differs from the original.
