When current flows through a conductor it becomes an inductor, when there is an inductor there is an electromagnetic field (EM). This can cause a variety of issues during PCB layout if you don’t plan ...

A typical Twin Feeder cable, or more popularly referred to as "Zip Cord", consists of two adjacent conductors separated by insulation, or commonly referred to a "dielectric". For convention we assume ...

When failure is not an option, high reliability EMI filters deliver superior high-frequency EMI suppression for ...

Inductors are set to join other electronic components in being miniaturized thanks to a quantum effect ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

Spoiler summary: The loop inductance of a circular loop is about 25nH per inch of circumference. Remember: before you start using rules of thumb, be sure to read the Rule of Thumb #0: Use rules of ...

Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters. Using the test setup ...

In the race for ever-improving technology, there are two related technical capabilities that drive our world forward: speed and size. These are related, as the smaller a device is, the less distance ...

The world’s energy demand is rising, and NREL’s ULIS power module could help meet it. Demand for energy worldwide is climbing rapidly, driven in part by power hungry data centers that support ...

[Apexys] is performing some experiments with switched-mode power supplies and needed to compare the inductance of the coils he was using. His multimeter doesn’t have an inductance testing function, ...
