This brief article is geared towards EMC test practitioners who are tasked with specifying broadband RF amplifiers for RF immunity testing and need to quickly get up-to-speed on the key factors involved in the buying decision before actually making the purchase of an expensive amplifier.

When two circuits share a return path with non-zero impedance, the result is common-impedance coupling — and real EMC problems. This foundations piece breaks down the theory with circuit models, then backs it up with lab measurements showing how ground impedance affects audio, video, and high-current circuits sharing a common return path.

When switches interrupt current through inductive loads, the results can be destructive — high-voltage spikes, HF ringing, and arcing that threatens both components and nearby circuits. This article breaks down the physics behind these transients and demonstrates practical, low-cost protection strategies.

We’ve queried training resources in our industry to provide you with an overview of free or affordable solutions to meet your training goals in 2018. You’ll find here sources of compliance-related seminars, workshops and other types of training, offered online and on location, public and private.

In this article, we’ll discuss what to do next. It won’t happen overnight, but with a plan (and some work), you can move from EMI-novice to EMI-expert.

When considering filters and filtered connectors to help eliminate noise issues in a system, determining the best EMI solution is based on the mechanical configuration of that system.

Symbol choices for your product safety labels can be complex – especially in light of the latest ISO standards update. This month, we look at some of the most pressing questions you may be facing.

ESD process control in factories where ESD-sensitive parts are being handled is the foundation for the manufacturing of high quality electronic products.

We are pleased to bring you Banana Skins, a new monthly column in In Compliance, and a 20-year tradition that began in the pages of the EMC Journal.
