“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.

EPCOS has developed two new ferrite materials whose improved properties make them suitable for the power range typical of SMPS and current meters. N95 is distinguished by a high flux density of 525 mT ...

Power architectures with nonisolated voltage regulation continue to evolve, and power inductor designs are fundamental to the success of the new product designs. The trend toward two-stage conversion ...
