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 ...

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 ...

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 ...

TDK has introduced ferrite ‘E’ cores up to 40 x 80 x 160mm for industrial applications such as motor drives. The largest one is made from N87 ferrite, while most of the rest also come in N88 or N97.

Vista, Calif. — ACME Electronics Corp. recently developed a new manganese-zinc ferrite material designed to reduce power losses in high-temperature power applications. The new material can also help ...
