the service life of hk250wv105 ℃ of sanhe niujiao electrolysis co., ltd. will be affected by different service environment, equipment and installation methods. according to international standards, the service life of niujiao aluminum electrolytic capacitor will be doubled when the temperature is reduced by 7 ℃. therefore, the service life of the horn aluminum electrolytic capacitor mainly depends on the internal temperature of the horn aluminum electrolytic capacitor. under the same conditions, the lower the core temperature, the longer the service life.
the same ox horn aluminum electrolytic capacitor manufacturers are different, the quality will be different, the price will be very different. the service life of ox horn aluminum electrolytic capacitor is limited. the longer the service life is, the higher the cost performance ratio is. we should correctly realize that quality is more important than price. the high-quality horn aluminum electrolytic capacitor has stable electrical performance and long service life, which is far more cost-effective than purchasing low-cost ones.
in practical application, the voltage, ripple current and switching frequency of the electrolytic capacitor will directly affect the life of the electrolytic capacitor. in use, surge voltage and instantaneous high voltage often occur. generally, under the voltage of 1.34 times of rated voltage, the phenomenon of liquid leakage and bottom flushing will occur in an hour. the main reason is the damage caused by surge voltage and instantaneous high voltage. therefore, the voltage selection of horn electrolytic capacitor will be reduced to 80% of the rated voltage reason.
as mentioned above, the higher the temperature is, the faster the evaporation rate of electrolyte will be. when the amount of electrolyte is reduced to a certain limit, the life of capacitor will be terminated. when installing, we should consider the following four points:
1. avoid installation in a sealed environment.
2. keep away from other heating elements during installation.
3. if conditions permit, install heat sink.
4. the temperature and time should be well controlled during welding.
