Aluminum Electrolytic Screw Terminal Snap-In Capacitors Slide 9

A detailed life calculation requires knowing the capacitor ESR at a given frequency and temperature, the thermal characteristics of the capacitor, and the relationship of life vs. hotspot temperature for that series. These are all contained within KEMET’s online life calculator. When considering a power electrolytic capacitor, use the “double the life for every 10°C decrease” rule just to make sure to apply the right range. Then enter the operating conditions into the online calculator, found on the next slide, to get an accurate operating life estimate. If a suitable capacitor cannot be found, an optimized solution may be the answer. Kemet has the capability of adjusting the parameters of the capacitor to meet special needs.
