Magnetic cores for power supply inductors require careful selection because of the important role they play. An inductor core must be able to retain inductance with dc bias and handle any ripple ...

This application note presents the types of core materials used in power inductors. It also briefly discusses the core saturation, core loss, as well as the Equivalent Series Resistance (ESR). This ...

Wound-toroid inductors have been the mainstay for desktop core voltage regulators (V CORE) for years. Historically, the bulky size, sloppy tolerances and high power losses of these inductors were not ...

Until recently, cost and the ability of a part to function in an application have driven the choice of inductors in desktop-computing systems' processor-voltage regulators. Designers have not been ...
