Richard Nute examines how transformers behave when subjected to transient overvoltage, both magnetically and capacitively.

Sometimes a ferrite is used to remove ringing in some applications as in power electronics or digital circuits.

Even in the arcane world of Conformity Assessment, surprises are afoot.

The leakage current measuring circuits in IEC 950 and those in North America are exactly the same.

When designing an EMI/EMC filter the orientation relative to source and victim is critical for high effectiveness. Can you save components in your filters?

According to statistics from the WiFi Alliance, 12 billion WiFi-enabled products have been deployed since the year 2000. Another 3 billion are expected to ship in 2016 alone, with device deployments doubling by 2020 (3 million every day).

This month in our series exploring the latest industry insight on effective product safety label design and symbol usage, we’ll focus on the importance of consistency in the use of symbols and formats for both product safety labels and facility safety signs. For many years, the U.S. Occupational Safety and Health Administration’s (OSHA) regulations for workplace safety signs were based on outdated 1941-era formats. That changed about two and a half years ago. In October 2013, OSHA incorporated the latest versions of the ANSI Z535 safety sign, tag and color standards into its safety regulations, aligning them with today’s best practices. Let’s look at how this change, which allows for consistent sign and label formats using the latest standards, is impacting our products and our workplaces.

Almost every safety standard has requirements addressing the accessibility of certain parts.

If you are a novice designer of electronic circuits, this is one of the best pieces of advice I can give you from my experience in EMI troubleshooting and training.

The paper discusses the importance of understanding the current distribution below a printed circuit board trace.
