load life: period of time, during which the technical parameters of all capacitors stay within the given limits. jianghai defnes this without allo wing for outliers. ? u seful life: defned like load life, but a given percentage of components may be o utside the defned limits. useful life data are usually calculated within a confdence level of 60%. see further details in specifcations and data she ets. outlier percentage: 1%. ? endurance t est: iec 60384-4 defnes the acceptable drift criteria of electrical parameters after the endurance tests (continuous voltage test). ? shelf life: defnition of time with acceptable drift of capacitor parameters after storage at upper category temperature without load. jis-c-5102- 1994 vibration and mechanical stress: capacitors are sensitive to vibration and mechanical forces applied on the leads. do not use capacitors, which have been dropped onto a rigid surface. i nsulation: if any defect of the sleeve is visible, the component should not be used C same for any kind of visible damage. a capacitor should be electrically isolated from the following parts: aluminum case, cathode lead wire, anode lead wire and circuit pattern, and auxiliary terminal of snap-in type. the pvc sleeve is not recognized as an isolator and therefore the standard capacitor should not be used in a place where insulation function is needed. please contact jianghai if higher grade of insulation is required. environmental conditions: ? a void direct contact with water, salt solution, oil, dewing conditions ? halogens generally , especially fumigation treatment with bromides and fame retardent agents containing halogens must be avoided. ? a void exposing to direct sunshine, ozone, ultraviolet rays and x-ray radiation. ? air pressure: max. 150kpa, min. 8kpa. ? no heavy air pressure changes are allowed. ? do not use or store in an environment containing any hazardous gas (e.g., hydrogen sulphide, sulphurous acid, nitrous acid, chlorine, amm onia, bromine, methyl bromide, other halogens) or acidic or alkaline solutions . storage: ? t emperature 5 to 30c, humidity below 75%. ? electrolytic capacitors may accumulate charge naturally during storage. in this case discharge through a 1kohm resistor before use (recovery v oltage). ? leakage current may be increased after long storage time. in th is case the capacitor should be subjected to the rated voltage treatment th rough a 1kohm resistor before use for 1 hour , then it should be discharged through a resistor of about 1 ohm/v olt. ? storage times above 1 year should be avoided or rated voltage t reatment may be necessary . ? in accordance to iec 60384-4 electrolytic capacitors are subjec t to a reforming process before acceptance testing. rated voltage is applied via a series resistance (100 : ur 100vdc, 1k: ur > 100vdc). soldering: soldering conditions (temperature, times) should be within specified conditions, especially for smd components. avoid high soldering temperatures as this may reduce lifetime or damage the capacitor. do never dip the capacitor body into molten solder. flux should not be adhered to the capacitors body but only to its terminals. for details and different methods please contact us. cleaning and coating: do not use fxing agents or cleaning substances containing halogens and the epoxy resin coating materials. also never use solvents containing: halogenated hydrocarbons, alkali, petroleum, trichloroethylene/-ethane, xylene, acetones, trichlorotrifuoroethane, tetrachloroethylene, methylenechloride, chloroform, acetates, ketones, esters, chlorides and bromides. in case of questions see detailed instructions. mounting: other devices, which are mounted near the capacitor, should not touch the capacitor. additional heat coming from other components near the capacitor may reduce the lifetime of the capacitor. do never bend or twist the capacitor after soldering to avoid stress on the leads. radial capacitors are not protected against mechanical forces on the leads. forces on the pins might damage the capacitor. no printed circuit board tracks are allowed between the lead pads of the capacitor. screw terminal capacitors should only be mounted in an upright position. transport: avoid fumigation and spraying insecticides (especially with bromides) in the import or export procedures which can cause corrosion. this applies also to the fnished devices. maintenance: periodical inspection should be carried out for the capacitor: visual inspection to check pressure relief open or leakage of electrolyte, electrical characteristics as leakage current, capacitance, and dissipatio n factor. electrolyte and separator paper: electrolyte and separator paper used in aluminum capacitors may be fammable. also electrolyte is electrically conductive. therefore in case electrolyte gets in contact with pc board it may cause corrosion of circuit pattern or cause short circuit between patterns, and may lead to smoke generation or ignition in worst case. caution during u s e of capacitors: do not touch the terminals of capacitors. keep the capacitor free from conductive solution, such as acids, alkali and so on. ensure that the operating environment of the equipment into which the capacitor has been built is within the specifed conditions mentioned in the catalogue or specifcation sheets. safety vent: the safety vent needs some free space to open properly. allow for free headroom of at least 2mm for diameter 16mm, more than 3mm for diameter 18-35mm, more than 5mm for case diameter 40mm and larger. emergency actions: when the pressure relief vent is open and some gas blows out from the capacitor, please turn the main switch of the equipment off or pull out the plug from the power outlet immediately. during safety vent operation, extremely hot gas (>100c) may blow out of the capacitors. do not stand close to the capacitors. in case of eye contact, rinse the open eye(s) with clean water immediately. in case of ingestion, gargle with water immediately, do not swallow. do not touch electrolyte but wash skin with soap and water in case of skin contact. definition of electrical parameters: separate documents as application notes, equivalent circuit diagrams and so on are available on request. packaging: please refer to the data book for details. further information is available on request. jianghai europe electronic components gmbh jianghai electrolytic capacitors v0712
