Hi-Flux cores are designed to operate up to about 6500 gauss, as opposed to the 3500 gauss limit of standard MPP cores. There is some sacrifice in stability because less distributed air gap is required to obtain the reduced permeabilities. Core losses are also higher than MPP, although because of their high flux and power-handling capabilities, HI-Flux cores are used as energy storage inductors and in line output (flyback) transformers in SMPS. They are also especially well suited for DC and line frequency noise filter inductors (such as the differential-mode choke in a switched mode power supply). Their high saturation flux density can be used to advantage because core loss is negligible at the low frequencies of these applications.
Disadvantages of Hi-Flux are:
Higher core losses than MPP
Advantages of Hi-Flux are:
Energy storage inductors used in switch-mode power supplies
