Electrolytic capacitors for DC application require polarization. Confirm the polarity.If used in reversed polarity,the circuit life may be shortened or the capacitor may be damaged.For use on circuits whose polarity is occasionally reversed,or whose polarity is unknown,use bi-polarized capacitors (BPseries).Also,note that the electrolytic capacitor cannot be used for AC application. 2. Do not apply a voltage exceeding the capacitor`s voltage rating. If a voltage execeeding the capacitor`s voltage rating is applied,the capacitor may be damaged as leakage current increases. When using the capacitor with AC voltage superimposed on DC voltage,care must be exercised that the peak value of AC voltage does not exceed the rated voltage. 3. Do not allow excessive ripple current to pass. Use the electrolytic capacitor at current values within the permissible ripple range.If the ripple current exceeds the specified value,request capacitors for high ripple current applications. 4. Ascertain the operating temperature range. Use the electrolytic capacitors according to the specified operating temperature range.Usage at room temperature will ensure longer life. 5. The electrolytic capacitor is not suitable for circuits in which charge and discharge are frequently repeated. If used in circuits in which charge and discharge are frequently repeated,the capacitance value may drop,or the capacitor may be damaged.Please consult our engineering department for assistance in these applications. 6. Apply voltage treatment to the electrolytic capacitor which has been allowed to stand for a long time. If the electrolytic capacitor is allowed to stand for a long time,its withstand voltage is liable to drop,resulting in increased leakage current.If the rated voltage is applied to such a product,a large leakage current occurs and this generates internal heat,which damaged the capacitor.If the electrolytic capacitor is allowed to stand for a long time,therefore,use it after giving voltage treatment (Note 1).(However,no voltage treatment is required if the electrolytic capacitor is allowed to stand for less than 2 or 3 years at normal temperature.) 7. Be careful of temperature and time when soldering. When soldering a printed circuit board with various,components,care must be taken that the soldering temperature is not too high and that the dipping time is not too long.Otherwise,there will be adverse effects on the electrical characteristics and insulation sleeve of electrolytic capacitors in the case of small-sized electrolytic capacitors,nothing abnormal will occur if dipping is performed at less than 260℃ for less than 10 seconds. 8. Do not place a soldering iron on the body of the capacitor. The electrolytic capacitor is covered with a vinyl sleeve.If the soldering iron comes in contact with the electrolytic capacitor body during wiring,damage to the vinyl sleeve and/or case may result in defective insulation,or improper protection of the capacitor element. 9. Cleaning circuit boards after soldering. Some solvents have adverse effects on capacitors. Please refer to the next page. 10.Do not apply excessive force to the lead wires or terminals. If excessive force is applied to the lead wires and terminals,they may be broken or their connections with the internal elements may be affectde.(For strength of terminals,refer to KS C IEC 60384-4(JIS C5101-1,JIS C5101-4) 11.Care should be used in selecting a storage area. If electrolytic capacitors are exposed to high temperatures caused by such things as direct sunlight,the life of the capacitor may be adversely affected.Storage in a high humidity atmosphere may affect the solderability of lead wires and terminals. 12.Surge voltage. The surge voltage rating is the maximum DC over-voltage to which the capacitor may be subjected for short periods not exceeding approximately 30 seconds at infrequent intervals of not more than six minutes.According to KS C IEC 60384 -4,the test shall be conducted 1000 cycles at room temperature for the capacitors of characteristic KS C IEC 60384-4 or at the maximum operating temperature for the capacitors of characteristics B and C of KS C IEC 60384-4 with voltage applied through a series resistance of 1000 ohms without discharge.The electrical characteristics of the capacitor after the test are specified in KS C IEC 60384-4.Unless otherwise specified,the rated surge voltage are as follows: Rated Voltage(V) 2 4 6.3 10 16 25 35 50 63 80 100 160 200 250 315 350 400 450 500 Rated Surge Voltage(V) 2.5 5 8 13 20 32 44 63 79 100 125 200 250 300 365 400 450 500 550 Note 1 Voltage treatment … Voltage treatment shall be performed by increasing voltage up to the capacitor`s voltage rating gradually while lowering the leakage current.In this case,the impressed voltage shall be in the range where the leakage current of the electrolytic capacitor is less than specified value.Meanwhile,the voltage treatment time may be effectively shortened if the ambient temperature is increased (within the operating temperature range).

Common type of halogenated cleaning agents are listed below. Structural Formula Chemical Name Representatice Brand Name Trichlorotrifluoroethane C 2CI3F3 Freon TF,Daiflon S-3 Fluorotrichloromethane CCI3F Freon-11,Daiflon S-1 1,1,1-Trichloroethane F2H 3CI3 Chloroethane Trichloroethylene C 2HCI3 Trichiene Methyl Chloride CH 3CI MC We would like to recommend you the below cleaning materials for your stable cleaning condition taking the place of previous materials. ◎Isopropyl Alcohol(IPA) or Water Cleaning method: One of immersion, ultrasonic or vapor cleaning. Maximum cleaning time: 5 minutes(Chip type: 2 minutes) ※Do not use AK225AES Aluminum electrolytic capacitors are easily affeceted by halogen ions,particularly by chloride ions. Excessive amounts of halogen ions,if happened to enter the inside of the capacitors, will give corrosion accidents-rapid capacitance drop and vent open. The extent of corrosion accidents varies with kinds of electrolytes and seal-materials. Therefore, the prevention of halogen ion contamination is the most improtant check point for quality control in our procuction lines. At present, halogenated hydrocarboncontained organic solvents such as Trichloroethylene, 1,1,1-Trichloroethane, and Freon are used to remove flux from circuit boards. If electroytic capacitors are cleaned with such solvents,they may gradually penetrate the seal portion and cause the eosion.When using latex-based adhesive on the capacitors rubber end seal for adhesion to a PCB, corrosion may occur depending on the kind of solvent in the adhesive. Select an adhesive as an organic solvent with dissolved polymer that is not halogenated hydrocarbon. Hot air drying is required for eliminating the solvent between the product and the PCB at 50℃~80℃ after coating. Followings are the penetration path of the halogenated solvent. ① Penetration between the rubber and the aluminum case ② Penetration between the rubber and the lead wire ③ Penetration through the rubber The inside of the capacitors,the mechanism of corrosion of aluminum electrolytic capacitors by halogen ions can be explainedas follows: Halides(RX) are absorbed and diffused into the seal portion. The halides then enter the inside of the capacitors and contact with the electrolyte of the capacitors. Where by halogen ions are made free by a hydrolysis with water in the electrolyte: + - RX + H2O → ROH + H + X - The halogen ions (X ) react with the dielectric substance(Al2O3) of aluminum electrolytic capacitors: + - AI2O3 + 6H + 6X →2ALX3 + 3H2O AIX3 is dissociated with water: + - ALX3 + 3H2O → AL（OH）3 + 3H + 3X SamYoung Electronics Co., Ltd.
