Most simple circuits you'll find for measuring reactive components cover only a limited range of component values. Here's a circuit built from a handful of inexpensive parts that will let you measure ...

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 ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

For the makers who need to construct their own capacitors, you must choose a dielectric for it, otherwise known as the material that goes between the plates. One popular material is paraffin wax that ...

Members can download the PDF ebook. We all know that capacitors have a shunt resistance (leakage) and that leakage resistance should be pretty easy to measure, right? Wrong! I've measured a lot of ...

Although many High-Q capacitors are available on the market their performance can vary widely depending on design and the quality of manufacturing, as Scott Horton of Johanson Technology explains to ...
