Curve Fit Equation Tool

The Curve Fit Equation Tool is an Excel file for design engineers working on calculations from the formulas in 2024 Magnetics Powder Core Catalog. Magnetic component engineers can compare the core performance including permeability vs. DC Bias, core loss density, normal magnetization, permeability vs. frequency, and permeability vs. temperature. Magnetics provides five comparison tables in this file based on 12 different powder core materials: MPP, High Flux, Kool Mu^®, Kool Mµ^® Ultra, Kool Mµ® MAX, Kool Mµ ^® Hƒ, XFlux^®, XFlux^® Ultra, High DC Bias XFlux^®, Edge, High DC Bias Edge^® and 75 Series.

To obtain Steinmetz parameters, substitute:

a for K_c
b for α
c for β
