Ensure Long Lifetimes from Electrolytic Capacitors: a Case Study in LED Light Bulbs

Authored on: Mar 29, 2013 by Mark Fortunato

Technical Paper / Application Note

More InfoLess Info
Electrolytic capacitors are notorious for short lifetimes in high-temperature applications such as LED light bulbs. The careful selection of these devices with proper interpretation of their specifications is essential to ensure that they do not compromise the life of the end product. This application note discusses this problem with electrolytic capacitors in LED light bulbs and provides an analysis that shows how it is possible to use electrolytics in such products.

It is certainly correct to be concerned about the lifetime of the capacitors and the rest of the driver circuit for LED lamps. Now is the time when the reputation is being developed, and if a lot of the devices fail then the adoption will be delayed by many years. Short CFL life was bad enough, but to have a $25 lamp bulb fail will leave a bad memory in consumers minds for many months or years.. So now certainly is the time to do it right.
