Developing electric vehicle components or drone systems? Learn how to set up an affordable benchtop conducted emission test during R&D. This pre-compliance approach helps engineers catch design issues early, avoid costly fixes, and gain insights into radiated emissions—all before formal testing begins.

The trend of progressively migrating both ESD and EMC immunity from the system/board to the component level is creating unprecedented challenges for the component ESD designer.

Although understanding each capacitor type and behavior is daunting and difficult to memorize, it is prudent that every aspiring engineer and technician involved in design for EMC at least have a rudimentary understanding of what capacitor technologies are available.

Electromagnetic compatibility (EMC) is the ability of electronic equipment to function properly without interference from noise sources and without causing disturbances to other electronic equipment. This article will help the reader understand the modes of electrical noise propagation, how fields interact, and the methods of testing for EMC, helping to provide the basis for designing low-emissions, low-susceptibility electronic equipment.

This article offers some useful insights and guidelines on how to effectively design and test systems using wide band gap devices to optimize product performance and achieve EMC compliance.
