Design

Transported lithium-based batteries are divided into two types: lithium-ion found in mobile phones and laptops, and non-rechargeable lithium-metal used in medical devices and a number of consumer grade AA, AAA and 9V batteries.

Compliance testing can be a very expensive endeavor and also a very confusing one. And when it comes to lithium ion cells and batteries, the expense is magnified by the number of samples needed for testing.

Software tools can give the EMC engineer a better chance to pass EMC requirements the first time.

When two circuits are in the vicinity of one another, a signal propagating in one circuit can induce a signal in another circuit, due to capacitive (electric field) and/or inductive (magnetic field) coupling between the circuits. This phenomenon is referred to as crosstalk.

Lithium batteries have been a staple of life for quite some time. However, their...

Ask a manufacturing engineer how to prevent electrostatic discharge (ESD) problems, and you will hear about ionizers, conductive floors, smocks, wrist straps, and more.

Known mechanisms that couple lightning surges onto communication cables, and how these mechanisms apply for the specific case of Ethernet cabling.

The purpose of this article is to provide an order in the design of the electronic system such that EMC considerations can be evaluated throughout the design effort, producing an electromagnetically compatible system at a minimal cost.

It is very common for people doing simulations to make a measurement of a similar set up to validate the simulation. This is a reasonable precaution since modern simulation tools will give a very accurate answer to whatever question it is asked.

This article will discuss one of the most prolific connectors in the electrical communication field, the RJ45 connector. Most LAN cables use these connectors, so this connector touches most of our lives every day.
