Metallized polymer film capacitors ageing law based on …
Ageing of metallized film capacitors. During their operating lifetime, capacitors may be subject to a variety of stresses that can irreversibly degrade their properties with time and cause their so-called "ageing". Among the numerous encountered ageing factors, voltage and temperature are the most prevalent stresses. 3.1. …

Capacitor Specifications: what they mean
Consider Operating Temperature in Selecting Capacitors. Environment factors are also needed to consider on how to select capacitors. If your product will be exposed to an environment temperature of 100''C, then do not use a capacitor that is only rated at 85''C. Likewise, if the minimum environment temperature is -30''C, then do not …
