When comparing published electrical values, engineers require a common basis for comparison. Ideally, a 100 nH inductor with a self resonant frequency (SRF) of 1 GHz from one manufacturer is ...

Often you find yourself in the position of needing to wind your own coil for a project, or maybe you come across an unmarked coil in the junk-box. How can you best find out its inductance? An ...

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 ...

How do you measure the value of an unknown inductor? If you have an LCR bridge or meter, you are probably going to use that. If not, there are many different techniques you can use. All of them rely ...

[Prof MAD] runs us through The Hidden Power of Inductors — Why Coils Resist Change. The less often used of the passive components, the humble and mysterious inductor is the subject of this video. The ...

Engineering consultant Frank Hertel outlines a method of measuring an inductor’s value using only an oscilloscope and a signal or function generator. In his work Frank does repairs and also fabricates ...

Using a previously derived circuit model, coupled inductor designs can be optimized for best performance in multiphase power converters. Any inductor or transformer with multiple windings is a coupled ...

Inductor selection for very-low-power or very-high-power energy conversion is not as simple a process as it is for the majority of power-supply designs. Off-the-shelf inductors from major suppliers ...
