(1) OPERATIONAL ENVIRONMENT, MOUNTING ENVIRONMENT AND CONDITIONS.
◎Ensure that operational and mounting conditions follow the specified conditions detailed in the catalog and specification sheets.
(2) OPERATING TEMPERATURE, RIPPLE CURRENT AND LOAD LIFE
◎Operating temperature and applied ripple current should be within the specified value in the catalog or specification sheets.
Ⅰ.Do not use Aluminum Electrolytic Capacitors at temperature which exceeds the specified category temperature range.
Ⅱ.Do not apply excessive current to the capacitors, which exceeds the specified rated ripple current.
◎During circuit design, please ensure that capacitors are selected to match with the lifetime requirements of the application.
◎Aluminum Electrolytic Capacitors are normally polarized. Reverse voltage or AC voltage should not be applied. When polarity of applied voltage is uncertain or when the polarity may flip over, nonpolar type capacitors should be used, but the nonpolar type cannot be used for AC circuit.
◎Standard Aluminum Electrolytic Capacitors are not suitable for rapid charge and discharge applications. Consult with HER MEI about specially designed capacitors for rapid charge and discharge.
(4) APPLIED VOLTAGE
◎Do not exceed the rated voltage of capacitors.
(5) CONDITIONS OF USE
◎The following environment should be avoided when using Aluminum Electrolytic Capacitors.
Ⅰ.Damp conditions such as water, saltwater spray, or oil spray or fumes. High humidity or humidity condensation situations.
Ⅱ.Hazardous gas/fumes such as hydrogen sulfide, sulfurous acid gas, nitrous acid, chlorine gas or ammonia.
Ⅲ.Exposure to ozone, ultraviolet rays or radiation.
Ⅳ.Severe vibration or shock which exceeds the condition specified in the catalog or specification sheets.
PCB BOARD CLEANING
◎Standard Aluminum Electrolytic Capacitors should be free from halogenated solvents during PW board cleaning after soldering. Use solvent proof capacitors and follow the specified cleaning condition when halogenated solvents are used.
◎Solvents should have well controlled conductivity, pH, specific gravity and water contents during the cleaning of solvent proof capacitors.
◎Cleaned PW board with capacitors should not be kept in solvent environment or nonventilated places. Let PW board containing capacitors after cleaning dry with hot blast fully. The temperature of such breeze should be under the upper category temperature of capacitors.
ADHESIVES AND COATING MATERIALS
◎Do not use halogenated adhesives and coating materials to fix Aluminum Electrolytic Capacitors.
◎Flux between the surface of the PW board and sealing of capacitors should be cleaned before using adhesives or coating materials.
◎Solvents should be dried up before using adhesives or coating materials. Do not cover up all the sealing area of capacitors with adhesives or coating materials, make coverage only partial.
◎Aluminum Electrolytic Capacitors should not be stored in high temperatures or where there is a high level of humidity. The suitable storage condition is 5℃－35℃ and less than 75% in relative humidity.
◎Aluminum Electrolytic Capacitors should not be stored in damp conditions such as water, saltwater spray or oil spray.
◎Do not store Aluminum Electrolytic Capacitors in an environment full of hazardous gas (hydrogen sulfide, sulfurous acid gas, nitrous acid, chlorine gas or ammonia).
◎Aluminum Electrolytic Capacitors should not be stored under exposure to ozone, ultraviolet rays or radiation.
