EMI filter design hinges on critical component placement. Learn how strategic orientation of capacitors and inductors can transform electromagnetic interference performance, potentially solving compliance issues with existing components and minimal design changes.

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.

Want to troubleshoot electronic circuits better? Arturo Mediano says it's all about being able to "see" what's going wrong. The key is looking at your signals in both time and frequency domains, and using the right tools - from basic voltage probes to fancy near-field scanners - to spot and fix those pesky EMI problems.

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).

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

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

Take time to check for EMI, efficiency, temperature, safety, immunity, or any other requirement in your product.

For the purposes of safety, what is “working voltage,” and what is its relevance to the safety of the equipment?

Ferrites for EMI suppression are usually chosen looking for high (resistive) impedance at the...
