WebTopic D1: Part Stress Derating . The practice of limiting electrical, thermal and mechanical stresses on parts to levels below their specified ratings is called derating. If a system is expected to be reliable, one of the major contributing factors must be a conservative design approach incorporating realistic derating of parts. WebParts stress analysis is conducted at a later stage of development and usually provides a lower, and more accurate MTBF figure. Unlike the parts count method, parts stress takes into account a great deal more information about each component, such as: ...
