4,IMPORTANT INFORMATION ON THE APPLICATION OF ALUMINUM ELECTROLYTIC CAPACITORS

(1)DC aluminum electrolytic capacitors are normally polarized

When reverse voltage is applied on DC aluminum electrolytic capacitor, the circuit will be short out and the capacitor will be damaged due to abnormal current flows through the capacitor. Please use non-polar types of capacitors when the positive voltage is applied on the cathode terminal.

(2)Use capacitor within rated voltage

When capacitor is used at higher voltage than the rated voltage, leakage current increased, characteristics drastically deteriorated and damaged in a short pried may occur as a result. Please take extra caution that the peak voltage should not exceed the rated voltage.

(3)Sudden charge and discharge

When aluminum electrolytic capacitors for general purpose-use are employed in rapid charge and discharge application, its life expectancy may be shortened resulted from capacitance decrease, heat rise, etc.

(4)Storage of the capacitor

Leakage current tends to increase when aluminum electrolytic capacitors have been stored for long period of time. The higher the storage temperature rise, the faster the leakage current increase. Please take caution when selecting the storage location. The leakage current will decrease gradually as voltage is applied to the capacitor. The capacitor is subjected to aging before using where increased leakage current may cause problems in the circuit.

(5)Use capacitor within rated ripple current

If excessive ripple current is applied on the capacitor, which will result in generating excessive heat inside, reducing capacitance and shorting life if capacitor. Therefore the peak value of the ripple voltage should be less than the rated value.

(6)Ambient temperature

Life of aluminum electrolytic capacitor is affected by the ambient temperature. It is generally know that the life

double for each 10°C decrease in temperature.

Accord with latest standard of RoHS, if customers have any special requirements, according to the relevant agreements which signed by both parts.

(7)Tensile strength of lead wire

When a strong force is applied to the lead wires or terminals, stress is put on the internal connections, which may result in short circuit, open circuit or increased leakage current. So it is not advisable to bend or handle a capacitor after it has been soldered to the PC board.

(8)Heat resistance at the soldering process

During soldering process, secondary shrinkage or crack of PVC sleeve may occur when soldering temperature is too high or soldering time is too long.

(9)Hole pitch and position of PC board

When designing a PC board, its hole pitch should be designed to coincide with the lead pitch (lead spacing) of the capacitor specified in the catalog or specification. When a capacitor is forcibly inserted into an unmatched hole pitch, a force will put on the leads and which could result in a short circuit or increased leakage current.

(10)Cleaning after soldering

1.The aluminum electrolyte capacitors should be fee halogenated solvents during board cleaning after soldering. Use solvent proof capacitors when halogenated solvents are used.

2.After cleaned with the solvent with should proof the quality of capacitors, the capacitors should not be kept in solvent environments of non-ventilated places. Let the capacitors after cleaning dry with hot blast fully above 10mins and the temperature of hot blast should not be over than specified upper limit of capacitors.

(11)Adhesives,fixative and coating and coating materials (coating agent)

1.Do not use halogenated adhesives and coating materials to fix aluminum electrolytic capacitors.

2.Do not cover up all the sealing area of capacitors with adhesives,fixative or coating materials (coating agent), make coverage only partial.
