As switching frequencies increase above 1 MHz, the question of inductor performance often arises. While the relative merits of specific inductors can be compared based on parametric data, it is most ...

Numerous variables and parameters are involved in building and specifying an inductor. Only a selected few give a designer limited degree of freedom. The rest, a majority, is utterly beyond the reach ...

“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.
