Iron Powder Core Frequency

Iron powder cores general material properties material reference permeability µo temp.

Iron powder core frequency.

This air gap has the disadvantage of power loss leading to the risk of a hot spot. They come in different mixes for use at different frequencies. Iron powder cores are more stable than ferrites and do not saturate as easily so they are best for tuned circuits filters and high power inductors. Carbonyl iron powders are basically constituted of micrometer size spheres of iron coated in a thin layer of electrical insulation this is equivalent to a microscopic laminated magnetic.

Use this al value and the formuia beiow to calcuiate the number of turns for a specific inductance. Iron powder toroidal cores for resonant circuits material 0 permeability1 freq. Kool mµ hƒ powder cores optimized for frequencies 200 500 khz are a cost effective solution for minimizing power losses in high frequency power supplies. Iron powder cores are commonly used in power conversion line filter applications and radio frequency applications.

For best q use the mix specified for your frequency to find the number of turns to give the desired inductance for your. G18 55 385 6 6 green red a good dc saturation characteristics. Oftentimes iron powder cores substitute ferrite cores. The al value of each iron powder core can be found in the charts on the next several pages.

Ppm oc material density g cm3 color note y8 35 255 6 5 yellow red a good high frequency material it has low core loss and good linearity under high bias conditions. Range 100mhz 300 mhz color tan core number o d.
