circuits

New developments in electronics manufacturing are increasingly dominated by the requirements of EMC today. Considerable follow-up costs in product development are caused due to the failure of electronic modules in EMC compliance tests. The integrated circuits that are used in an electronic system are critical for its EMC performance as a whole. ICs are often responsible for interference emissions or immunity weak points and it is difficult to gain control of them in such cases.

Every EMI (electromagnetic interference) problem ultimately starts or ends at an electronic circuit. And since electronic components are the building blocks of circuits, it only makes sense to pay attention to the EMI impact of those individual components.

Probably the most important thing to remember about electronic components is that nothing is ideal. Components change values with frequency, current, voltage, and even physical size. And those changes may be nonlinear, adding a new level of complexity. Like a pilot, you need to know the limits so you stay within the envelope of safe performance.
