Abstract: Electrolytic capacitors are notorious for short lifetimes in high-temperature applications such asLED light bulbs. The careful selection of these devices with proper interpretation of their specifications isessential to ensure that they do not compromise the life of the end product. This application notediscusses this problem with Electrolytic capacitors in LED light bulbs and provides an analysis that showshow it is possible to use Electrolytics in such products.
