This article presents the fundamentals and application of capacitors. What is a capacitor, and how do we select them? Techniques of selecting capacitors and things to consider when using capacitors are highlighted. Both practical examples and simulation are used to demonstrate the key points.
Heat flow analysis for semiconductor ESD situations can be approximated to one dimension, and then captured with a generalized Ohm’s Law using a complex impedance. Methods can include time-dependent electrothermal pulses and feedback due to self-heating, with solutions readily carried out on any desktop computer.
The shielding performance of bayonet vs. threaded connectors is measured and some possibly surprising conclusions are drawn. Bayonet connectors – more useful than you might think.
This article describes three troubleshooting methodologies doctors use to diagnose (troubleshoot) medical problems. These same techniques have proven useful in my own EMC consulting practice.
End-product manufacturers can help protect against supply chain disruptions that impact the availability of listed or recognized components by proactively identifying suppliers who can provide substitute components that conform with their listing requirements.
Our knowledge of ESD and how to control it has grown significantly over the past 50 years. This article maps the history of that journey.
Traditionally, the start of a new year is a time when we reflect on the progress we’ve made during the year passed and set our goals for the new year. 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 2021.
This article analyzes the V-I characteristic of a varistor and shows it is more appropriate to treat the varistor as a current dependent resistance rather than the conventionally taught voltage dependent resistance. Spice circuit examples are given, based on a current dependent resistance varistor model.
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 2020.
For engineers new to the field of EMC, the road can look very steep indeed. But, with a plan (and some work!), you can grow from EMC-novice to EMC-expert.
