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.

Abstract: There are differences between the operation of low-frequency AC transformers and electronic transformersthat supply current to MR16 lamps, and there are also differences in the current draw for MR16 halogen lamps andMR16 LED lamps. These contrasts typically prevent an MR16 LED lamp from operating with most electronictransformers. This article explains how a high-brightness (HB) LED driver optimized for MR16 lamps will allow LEDlamps to be compatible with most electronic transformers.A similar version of this article appeared on Display Plus, July 7, 2012 and in German in Elektronikpraxis, October 1,2012.
