Capacitors Derating and Category Concepts
There are two most common derating parameters: voltage (that may include hidden current limitation) and temperature. The derating factors are typically in "OR", "whatever is greater" logic relationship, so if the voltage derating rule says 20% and due to the temperature you have to derate 30% as well, "whatever is greater" condition …
