Why will aluminum shell electrolytic capacitor become the bottleneck component of LED bulb life?

Time:2021/08/12 Visits:1554
Aluminum shell electrolytic capacitor is a common characteristic of power supply in daily life. Aluminum shell electrolytic capacitor is affected by high and low temperature conditions, and its service life is limited.

The evaporation rate of electrolyte is closely related to the temperature of aluminum shell capacitor. When the working temperature drops by 10 ℃, the service life of aluminum shell capacitor will be doubled. The rated life of aluminum shell capacitor is usually the result obtained at its large rated temperature. Typical rated life is 1000 hours at 105 ° C. When these aluminum shell capacitors are selected for long-life applications such as LED bulbs, the service life of LED is 25000 hours, and the service life of aluminum shell capacitors becomes a problem. In order to achieve a life of 25000 hours, this aluminum shell capacitor requires an operating temperature of no more than 65 ℃. This operating temperature is particularly challenging because in this application, the ambient temperature will exceed 125 degrees Celsius.

There are not many capacitors with high rated temperature in the market, but in most cases, aluminum shell electrolytic capacitors will become the bottleneck component of LED bulb life.

If you want to know more about aluminum shell capacitors, please continue to pay attention to Wuxi Fusheng Electric Appliance Co., Ltd., which produces aluminum extrusion products, plastic parts, aluminum caps of capacitor iron caps, aluminum shells of capacitors, aluminum bottles, aluminum cans of tea boxes and other aluminum shells. The company has strong technical force, complete testing means and production equipment.
