When designers think of passive components, they think of manufacturing tolerances for inductors and capacitors that are typically ± 20% or ± 10%. That's okay in theory, but not when these components ...

Most modern electronic devices consist of several key components: transistors, capacitors, resistors, inductors and diodes. Often, they are supplemented by additional components like crystals and ...

Researchers at the University of Illinois, Urbana-Champaign have devised a method of combining capacitors and inductors in a tiny, 3D rolled membrane. This will save space in the electronic filters ...

Inductors have the exact opposite characteristics of capacitors. Inductors store energy in a magnetic field (produced by the current through wire), whereas capacitors store energy in an electric field ...

When designing or optimizing a VRM (voltage Regulation Module), we need its output impedance data and impedance data for the filter inductors and capacitors for us to have complete simulation models.

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

Giovanni D’Amore discusses approaches to characterising both dielectric and magnetic materials using impedance analysers and specialist fixtures. We are used to thinking about technological progress ...

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 ...
