Permeability is the measure of the ability of a material to support the formation of a magnetic field within itself or more simply, the inductance per unit length. This is less than the 5 Oe in the datasheet, so the core is not saturated. This is not true when using SI units, where $\mu_0 = 4\pi\cdot10^ The nice thing about G/Oe is that the permeability of air or vacuum (conventional symbol: $\mu_0$) is 1G/Oe, so permeability in G/Oe is also relative permeability, which is usually what inductance calculators expect.
This table doesn't specify units, but it could be gauss/ oersted or G/Oe, which are CGS units. The first, and simplest measure of permeability is in the table, under initial permeability. ) of the inductor, but it all cases, higher permeability means more inductance per turn of wire. The complete equations to calculate inductance are complex and depend on the geometry (E-I, toroid, wire gauge, turn spacing, number of turns. To know what inductance our coil will have, we need to know the permeability of the core material. at what current will this inductor saturate?.what losses will this core material introduce?.
