This non-linear current source value electrolytic capacitor so to get rid of electrolytic capacitors is due to two reasons:
Electrolytic capacitor life expectancy is short this is actually a misunderstanding of ordinary people. Of course, this misconception is obtained from a number of instances. Its primary reason is filled with many of the defective electrolytic capacitors on the Chinese market, the electrolytic capacitor life expectancy is very short indeed. But that does not mean their life electrolytic capacitors number whenever it certainly short.
Electrolytic capacitors, there are two, one is a liquid electrolyte, and the other is a solid electrolyte. Compare the number of liquid electrolytic capacitor life is short, it is because the liquid will dry reason. So the new longevity electrolytic capacitors on the selection of the number of solid electrolyte. The solid electrolytic capacitor life, said data can arrive 23 years, far beyond the life expectancy of the LED. But compare the cost of expensive solid electrolytic capacitors.
It is not a liquid electrolytic capacitors can not achieve longevity advantages? Completely not the case, the industry knows that Ruby electrolytic capacitor life expectancy in Japan at 105 ℃ can arrive at 10,000 hours, and the temperature dropped 10 degrees each, to extend life expectancy doubled in the ambient temperature of 85 degrees can have 40,000 hours, at 75 degrees will be able to have 80,000 hours, LED demand was satisfied completely. And the cost is not expensive to not bear degree. The company also recently opened Ruby announced a longer life than doubled the number of small volume LLE series electrolytic capacitors, life expectancy up to 20,000 hours of their time 105 ℃, which specializes in the use of small size bulb. And domestic manufacturers have also been able to produce and liquid electrolytic capacitors Bimei a ruby. So the original life expectancy of the electrolytic capacitor is not in doubt.
