Inductors are not the most common component these days and variable ones seem even less common. However, with a ferrite rod and some 3D printing, [drjaynes] shows how to make your own variable ...

“Drum core” is used to describe the shape of the ferrite core used in some power inductors, and it differentiates these inductors from other types such as toroidal, power bead, flat coil, or planar.

When choosing a conductor for use in an electronic circuit, there are several important properties that may need to be considered. The wire thickness and resistivity determines the current carrying ...

We report a fabrication technology for 3D air-core inductors for small footprint and very-high-frequency power conversions. Our process is scalable and highly generic for fabricating inductors with a ...
