Uprating is a process to assess the ability of a part to meet the functionality and performance requirements of the applications in which the part is used outside the manufacturers’ specification range. However, uprating can be an expensive and time consuming process. There is also no guarantee that all parts can be successfully uprated. In 2002, some electronic part manufacturers began releasing a category of parts considered to be “closer” to military-grade parts, called “Enhanced Plastic (EP)“…
