Export regulation of the capacitors for pulse use (750V or higher) and the capacitors for high voltage (5,000V or higher) is carried out according to (item 41-4) in Section 2 of Appendix Table 1 (Section 49 in Chapter 1 of METI's Ordinance) and (item 7) in Section 7 of Appendix Table 1 (Section 6 in Chapter 6 of METI's Ordinance). However, the aluminum electrolytic capacitors, which are described in this specification, don't fulfill the regulated level. Therefore, the aluminum electrolytic capacitors are not applicable to Export Trade Control Ordinance. (2) Export Trade Control Ordinance (Section 16 of Appendix Table 1 ) The aluminum electrolytic capacitors, which are described in this specification, are applicable to goods under Export Regulations (Category 85 of Appendix Table in Customs Tariff Law) based on Section 16 of Appendix Table 1 in Export Trade Control Ordinance. If the exporter got information that their export goods can be used in the development of weapon, the exporter must apply for exporting permission to Ministry of Economy, Trade and Industry (METI), and get METI's approval. Regardless of the above, if the exporter is notified by METI that his/her export goods can be potentially used in the development of weapon, the exporter must seek permission from METI to export, and get METI's approval. When Nippon Chemi-Con receives such notice from METI, we will inform your company of that. 9.2 Cleaning PC board These products are not solvent-proof type. 9.3 Manufacturing plant CHEMI-CON FUKUSHIMA CORPORATION(JAPAN) CHEMI-CON (MALAYSIA) SDN.BHD.(MALAYSIA) 9.4 For aluminum electrolytic capacitors, please refer to PRECAUTIONS AND GUIDELINES. Nippon Chemi-Con Corporation G150271L5012Z2 - 7 Precautions and Guidelines (Aluminum Non-Solid Electrolytic Capacitors) 【1】Device circuits design considerations 1) Confirm installation and operating requirements for capacitors, then use them within the performance limits prescribed in this catalog or product specifications. 2) Polarity Aluminum electrolytic capacitors are polarized. Never apply a reverse voltage or AC voltage. Connecting with wrong polarity will short-circuit or damage the capacitor with the pressure relief vent opening early on. To identify the polarity of a capacitor, see the relevant diagram in the catalogs or product specifications, or the polarity marking on the body of the capacitor. Incidentally, the rubber end seal bungs of the radial lead type capacitors have a solder-flux gas escaping configuration, which is nothing to do with the polarity of the capacitors. For circuits where the polarity is occasionally reversed, use a bi-polar type of aluminum electrolytic capacitor. However, note that even bi-polar type capacitors must not be used for AC circuits. 3) Operating voltage Do not apply an over-voltage that exceeds a rated voltage specified for the capacitors. The total peak value of the ripple voltage plus the DC voltage must not exceed the rated voltage of the capacitors. Although capacitors specify a surge voltage that exceeds the full rated voltage, it does not assure long-term use but limited use under specific conditions. 4) Ripple current Do not apply an overcurrent that exceeds the rated ripple current specified for the capacitors. Excessive ripple current will increase heat production within the capacitors, causing the capacitors to be damaged as follows: ・Shorten lifetime ・Open pressure relief vent ・Short circuit The rated ripple current is specified along with a specific ripple frequency. Where using the capacitors at any other ripple frequency other than the specified frequency, calculate the allowable ripple current by multiplying the rated ripple current by a frequency compensation factor (Frequency Multiplier) specified for each product series. 5) Operating temperature (Category temperature) Do not apply high temperatures that exceed the upper limit of the category temperature range specified for the capacitors. Using the capacitor at temperatures higher than the upper limit will considerably shorten the lifetime of the capacitor and make the pressure relief vent open. In other words, lowering ambient temperatures will extend the expected lifetime of the capacitors. 6) Lifetime Select the capacitors to meet the service life requirements of a device. 7) Charging and discharging Do not use capacitors in circuits intended for rapid charge and discharge cycle operations. If capacitors are used in the circuits that repeat a charge and discharge with a large voltage drop or a rapid charge and discharge at a short interval cycle, capacitance will decrease and/or the capacitors will be damaged by internal heat generation. Consult us for a heavy charge and discharge type of capacitor so that the capacitor will be designed in accordance with requirements of duty cycle of charge and discharge, the number of cycles, discharging resistance and operating temperatures. 8) Failure mode of capacitors Non-solid aluminum electrolytic capacitors have a limited lifetime which ends in an open circuit failure mode, in general. Depending on the product type and operating conditions, the failure mode may involve in opening of the pressure relief vent. 9) Capacitor insulation Electrically isolate the following sections of a capacitor from the negative terminal, the positive terminal and the circuit patterns. ・The outer can case of a non-solid aluminum capacitor. ・The dummy terminal of a snap-in type non-solid aluminum capacitor, which is designed for mounting stability. 10) Outer sleeve The outer sleeve of a capacitor does not assure electrical insulation (except for screw-terminal type capacitors). It should not be used where electrical insulation is required. 11) Operating conditions Do not use/expose capacitors to the following conditions: (1) Direct contact with water, salt water or oil, or high condensation environment. (2) Direct sunlight. (3) Toxic gases such as hydrogen sulfide, sulfurous acid, nitrous acid, chlorine and its compounds, bromine and its compounds and ammonium. (4) Ozone, ultraviolet rays or radiation. (5) Extreme vibration or mechanical shock that exceeds limits in the catalogs or product specifications. The standard vibration condition is applicable to JIS C 5101-4. Nippon Chemi-Con Corporation CAT.NO.E1001P - 1/5 12) Mounting (1) Non-solid aluminum electrolytic capacitors contain paper separators and electric-conductive electrolyte that contains organic solvent as main solvent material, both of which are flammable. If the electrolyte leaks onto a printed circuit board, it can erode the device circuit pattern, may short-circuit the copper traces, smoke and burn. Make sure of designing a PC board as follows: ・Provide the appropriate hole spacing on the PC board to match the terminal spacing of a capacitor. ・ Provide the following adequate clearance space over the pressure relief vent of a capacitor to avoid blocking the correct opening of the pressure relief vent.  Case diameter  Clearance φ 8(6.3) to φ 16mm : 2mm minimum φ 18 to φ 35mm : 3mm minimum φ 40 mm and above : 5mm minimum ・Do not locate any wire or circuit pattern over the pressure relief vent of a capacitor. ・ If a capacitor is mounted with its pressure relief vent facing down on the PC board, provide a ventilation hole in the board beneath it to let gas escape when the vent opens. ・Do not print any copper trace under the seal (terminal) side of a capacitor. Copper traces should be 1 mm (preferably 2mm or more) spaced apart from the side of the capacitor body. ・Avoid locating any heat source components near capacitors or on the opposite side of the PC board under capacitors. ・In designing a double-sided PC board, do not locate any through-hole via or unnecessary hole underneath a capacitor. ・In designing a double-sided PC board, do not print any circuit pattern underneath a capacitor. (2) For a screw terminal type capacitor, tightening the terminal screws and the mounting clamp should be within the maximum torque specified in the catalogs or product specifications. Do not mount a screw terminal type capacitor with the terminals facing downward. Also, if the body of a capacitor is installed horizontally such as being laid on its side, do not position the pressure relief vent downward. (3) For a chip type capacitor, design the land patterns of the PC board in accordance with the recommended footprint dimensions described in the catalogs or product specifications. 13) Using capacitors for significantly safety-oriented applications Consult us about capacitors for a device application affecting human safety ( ① Aviation and space, ② Nuclear, ③ Medical and ④ Vehicle) or for any device whose failure will make an impact on society. Note that some products such as photoflash use capacitors which have been designed for specific applications cannot be used for any other application. 14) Others Design device circuits taking into consideration the following conditions: (1) Electrical characteristics of a capacitor depend on the temperature and frequency. In designing the device circuits, consider the change in the characteristics. (2) If using more than one capacitor connected in parallel, design the device circuits to balance the current flow in individual capacitors. (3) If using more than one capacitor connected in series, connect shunting resistors in parallel with the individual capacitors to balance the voltage. 【2】Installation 1) Assembling (1) Do not try to reuse the capacitors once assembled and electrified, except only capacitors that are taken from a device for periodic inspection to measure their electrical characteristics. (2) Capacitors may have been spontaneously recharged with time by a recovery voltage phenomenon. In this case, discharge the capacitors through a resistor of approximately 1k Ω before use. (3) If non-solid aluminum electrolytic capacitors have been stored at any conditions more than 35℃ and 75% RH for long storage periods of time more than the limits specified in the catalogs or product specifications, they may have high leakage current. In this case, make pre-conditioning by applying the rated voltage through a resistor of approximately 1k Ω . (4) Confirm the rated capacitance and voltage of capacitors before installation. (5) Confirm the polarity of capacitors before installation. (6) Do not try to use the capacitors that were dropped to the floor and so forth. (7) Do not deform the can case of a capacitor. (8) Make sure that the terminal spacing of a capacitor equals the holes spacing on the PC board before installing the capacitor. For radial lead type capacitors, some standard pre-formed lead types are also available. (9) When installing a snap-in type capacitor on the PC board, insert the terminals into the holes and press the capacitor down until the body is settled flush on the surface of the PC board (without the body standing off). (10) Do not apply excessive mechanical force to capacitors more than the limits prescribed in the catalogs or product specifications. Avoid excessive mechanical force while the capacitors are in the process of vacuum-picking, placing and positioning by automatic Nippon Chemi-Con Corporation CAT.NO.E1001P - 2/5 mounting machines or cutting the lead wires by automatic insertion machines. 2) Soldering and heat resistance (1) For soldering using a soldering iron, consider the following conditions: ・Soldering conditions (temperature and time) should be within the limits prescribed in the catalogs or product specifications. ・If it is necessary to pre-form the terminal spacing of a capacitor to match the hole spacing on the PC board before assembly and soldering, do not make mechanical stress reach into the body of the capacitor but only the lead wires. ・Do not touch the body of a capacitor with the hot tip of the soldering iron. (2) For flow soldering, consider the following conditions: ・Do not dip the body of a capacitor into a solder bath. Expose only the terminals to the melt solder with the PC board interposing between the solder and the body of the capacitor. Solder only the reverse side of the PC board where the body of the capacitor is not located. ・Soldering conditions should be within the limits prescribed in the catalogs or product specifications. ・Do not apply flux to any part of a capacitor other than the terminals. ・Do not let any other component lean against not come into contact with the capacitor while soldering. (3) For reflow soldering, consider the following conditions: ・Soldering conditions (preheat, reflow temperature and time) should be within the limits prescribed in the catalogs or product specifications. ・When using the infrared heater and setting its temperatures, adjust the heating levels taking into consideration that the color and materials of a capacitor vary in their infrared absorbance. ・The allowable number of reflow passes is specified in the catalogs or product specifications. ・When mounting a capacitor on the double-sided PC board, do not place any wiring pattern underneath the capacitor. ・Please consult us about vapor phase soldering (VPS). (4) Do not try to reuse the capacitor that was removed from the PC board after soldering. (5) Only use chip type capacitors for reflow soldering. The other type capacitors are not designed for the reflow. 3) Handling after soldering After soldering the PC board, do not apply the following mechanical stress to the capacitor: (1) Do not tilt, push down or twist the body of the capacitor. (2) Do not grab the body of the capacitor to carry the assembly board. (3) Do not hit anything against the capacitor. When stacking the assembled boards, do not put any of the PC boards or other components against the capacitor. (4) Do not drop the assembled board. 4) Cleaning assembly boards (1) Do not clean capacitors with the following cleaning agents: ・Halogenated solvents : cause capacitor failures due to corrosion. ・Alkali system solvents : corrode (dissolve) the aluminum can case. ・Terpene and petroleum system solvents : deteriorate the rubber seal materials. ・Xylene : deteriorates the rubber seal materials as well. ・Acetone : erases the markings printed on a capacitor. Where cleaning is necessary, use only solvent resistant type capacitors that have been assured for the cleaning within the specific cleaning conditions prescriber in the catalogs or product specifications. In particular, carefully set up the conditions for ultrasonic cleaning system. (2) Where cleaning the solvent resistance type of aluminum electrolytic capacitors, confirm the following conditions: ・Control the contamination (the conductivity, pH, specific gravity, water content, etc.) of the cleaning agents. ・After the cleaning, do not leave the capacitors (assembly boards) in an environment of cleaning agent-rich or in a closed container. Sufficiently evaporate the residual cleaning agent from the assembly boards and the capacitors by forced hot air at temperatures less than the upper limit of category temperature range for more than 10 minutes. In general, aluminum electrolytic capacitors are sensitive to contamination of halogen ions (particularly to chlorine ions). Depending on the properties of the electrolyte and rubber seal materials used in a capacitor, the halogen ions lead up to catastrophic failures on the capacitor. Where the inside of a capacitor has been contaminated with more than a certain amount of halogen ions and the capacitor is in use, the corrosion reaction of aluminum occurs. The corrosion causes the capacitor to have a significant increase in leakage current with heat produced, open the pressure relief vent and become open circuit mode failure. Due to global environmental issues (greenhouse effects and other environmental destruction by depletion of the ozone layer), the conventional cleaning solvents of CFC 113, Trichloroethylene and 1,1,1-tricholoroethylene were replaced by substitutes. The following are some substitute cleaning agents and allowable cleaning conditions: a) Fatty-alcohol cleaning agents Pine Alpha ST-100S (Arakawa Chemical) Clean Through 750H, 750K, 750L and 710M (Kao) Technocare FRW-14, 15, 16 and 17 (Momentive Performance Materials) Nippon Chemi-Con Corporation CAT.NO.E1001P - 3/5 [Cleaning conditions] Either of immersion or ultrasonic cleaning, for a maximum of 10 minutes and at a maximum liquid temperature of 60℃ is acceptable. Make sure that the markings on the capacitor are not rubbed against any other component or the PC board during cleaning. Note that shower cleaning affects the markings on the capacitor. b) HCFC (Freon 225) as Alternative CFCs AK225AES (Asahi Glass) [Cleaning conditions] Solvent resistant type capacitors, which were originally developed to intend to resist Freon TE or Freon TES, are also capable of withstanding any one of immersion, ultrasonic or vapor cleaning, for a maximum of 5 minutes (or 2 minutes for KRE and KRE-BP series capacitors or 3 minutes for SRM series). However, this type of cleaning agent is not recommended to use, as the cleaning materials may be banned in near future in view of global environmental issues. c) IPA (Isopropyl Alcohol) Immersion cleaning with a maximum flux concentration of 2 wt% is acceptable. 5) Adhesives and coating materials (1) Do not use any adhesive or coating materials containing halogenated solvents. (2) Make sure of the following conditions before applying adhesive or coating materials to a capacitor, ・No flux residue nor stain is left between the rubber seal of a capacitor and PC board. ・Dry the capacitor to remove residual cleaning agents before applying adhesive and coating materials. Do not cover up the entire surface of the rubber seal of the capacitor with adhesives or coating materials. ・Heating and curing conditions for adhesives and coating materials should be followed as prescribed in the catalogs or product specifications. ・Covering up the entire surface of the rubber seal with resin mold materials will obstruct the normal diffusion of internal hydrogen gas from a capacitor and result in serious failures. Also, where the adhesive and coating materials contain a large amount of halogen ions, the halogen ions will contaminate the inside of the capacitor through the rubber seal materials, causing the capacitor to become a failure. ・Depending on solvent materials that the adhesive or coating materials contains, note that the outer sleeve of a capacitor may lose a gloss or whiten in appearance. 6) Fumigation In exporting or importing electronic devices, they may be exposed to fumigation with halide such as methyl bromide. Where aluminum electrolytic capacitors are exposed to halide such as methyl bromide, the capacitors will be damaged with the corrosion reaction with halogen ions in the same way as cleaning agents. For the export and import, Nippon Chemi-Con considers using some packaging method and so forth so that fumigation is not required. For customers to export or import electronic devices, semi-assembly products or capacitor components, confirm if they will be exposed to fumigation and also consider final condition of packaging. (Note that either cardboard or vinyl package has a risk of fumigation gas penetration.) 【3】Precautions during operation of devices 1) Never touch the terminals of a capacitor directly with bare hands. 2) Do not short-circuit between the capacitor terminals with anything conductive. Also, do not spill any conductive liquid such as acid or alkaline solution over a capacitor. 3) Confirm environmental conditions where the device will be placed. Do not use the devise in the following environmental conditions: (1) Water or oil spatters, or high condensation environment. (2) Direct sunlight. (3) Ozone, ultraviolet rays or radiation. (4) Toxic gases such as hydrogen sulfide, sulfuric acid, nitrous acid, chlorine and its compounds, bromine and its compounds and ammonium. (5) Extreme vibration or mechanical shock that exceeds the limits in the catalogs or product specifications. The standard vibration condition is applicable to JIS C 5101-4. 【4】Maintenance inspections 1) For industrial use capacitors, make periodic inspections of the capacitors. Before the inspections, turn off the power supply of the device and discharge the electricity of the capacitors. Where checking it by a volt-ohm meter, confirm the polarity beforehand. Do not apply mechanical stress to the terminals of the capacitors during inspection. 2) Characteristics to be inspected (1) Significant damage in appearance: vent opening, electrolyte leakage, etc. (2) Electrical characteristics: leakage current, capacitance, tan δ and other characteristics prescribed in the catalogs or product specifications If finding anything abnormal on the characteristics above, check the specifications of the capacitor and take appropriate actions such as replacement. Nippon Chemi-Con Corporation CAT.NO.E1001P - 4/5 【5】Capacitor venting 1) A capacitor with more than a certain case size has the pressure relief vent functioning to escape abnormal gas pressure increase. If gas expels from a venting capacitor, disconnect the power supply of the device or unplug the power supply cord. If not disconnecting the power supply, the device circuit may be damaged due to the short circuit failure of the capacitor or short-circuited with the liquid that the gas was condensed to. It may cause secondary damages such as device burnout in the worst case scenario. The gas that comes out of the open vent is vaporized electrolyte, not smoke. 2) The gas expelled from a venting capacitor is more than100°C. Never expose your face to the capacitor. If your eyes are exposed to the gas or you inhale it, immediately flush your eyes and/or gargle with water. If the electrolyte comes in contact with the skin, wash with soap and water. 【6】Storage 1) Do not store capacitors at high temperature or high humidity. Store the capacitors indoors at temperatures of 5 to 35℃ and humidities of less than 75% RH. In principle, aluminum electrolytic capacitors should be used within three years after production. 2) Keep capacitors packed in the original packaging material wherever possible. 3) Avoid the following storage environmental conditions: (1) Water spattering, high temperatures, high humidity or condensation environment. (2) Oil spattering or oil mist filled. (3) Salt water spattering or salt filled. (4) Acidic toxic gases such as hydrogen sulfide, sulfuric acid, nitrous acid, chlorine, bromine and methyl bromide filled. (5) Alkaline toxic gases such as ammonium filled. (6) Acid or alkaline solutions spattering. (7) Direct sunlight, ozone, ultraviolet rays or radiation. (8) Extreme vibration or shock loading 4) JEDEC J-STD-020 is not applicable. 【7】Capacitor disposal Please consult with a local organization for the proper disposal of industrial waste. For incinerating capacitors, apply a hightemperature incineration (over 800 ℃ ). Incinerating them at temperatures lower than that may produce toxic gases such as chlorine. To prevent capacitors from explosion, punch holes in or sufficiently crush the can cases of the capacitors, then incinerate. 【8】About AEC-Q200 The Automotive Electronics Council (AEC) was originally established by American major automotive manufactures. Today, the committees are composed of representatives from the sustaining Members of manufacturing companies in automotive electrical components. It has standardized the criteria for stress test qualification and reliability test for the electronic components. AEC-Q200 is the reliability test standard for approval of passive components, it has been specified test subjects and quantity etc. for each components. Criteria of reliability tests for Aluminum Electrolytic Capacitors are also described in this. As customer requirement, Chemi-Con has submits the test results according to AEC-Q200 for the Aluminum Electrolytic Capacitors used in automotive applications to increase in recent years.
