Iron Powder Core

Our optimized alloys like oc and od are formulated specifically to deliver exceptional dc bias or core loss performance.

Iron powder core.

The al value of each iron powder core can be found in the charts on the next several pages. For e cores 100 turns will be used as the standard testing criteria. Iron powder toroidal cores for resonant circuits material 0 permeability1 freq. Range 100mhz 300 mhz color tan core number o d.

Use this al value and the formuia beiow to calcuiate the number of turns for a specific inductance. 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. Iron powder toroidal cores will always have higher inductance measurement reading than expected if the number of turns is low resulting in winding not evenly distributed throughout the core. Micrometals alloy powder cores are becomming increasingly popular for emerging applications in 5g hardware and power systems due to their high efficiency and reliability.

For 4 1 50 200 or 75 300 ohm transmission line transformers in the range of 1 8 30 mhz select the size appropriate for the power level as follows. Iron powder cores general material properties material reference permeability µo temp. Because it hasn t been conducted in the high temperature so it s used temperature is 65c 125c. Iron powder cores is a magnetic core which use traditional production arts after the pure powder which content of fe is more than 99 surface insulation coating and then mixed pressed with organic binder.
