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 ...

I was involved with high-voltage power supplies in which transformers were wound using 3019-sized ferrite cores. Transformer structures were essentially the following: Figure 1 Pot core based ...

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.
