However, under certain conditions, the system (this product connected to a target application circuit) may emit individual electromagnetic component frequencies which exceed the maximum values allowed by the above mentioned standards. The frequency and magnitude of the emissions will be determined by several factors, including layout and routing of the target application with which the product is used.
