Iron Powder Core

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.

Iron powder core.

For high power feed line chokes choose the inside diameter of the iron powder core closest to the transmission line outside diameter and use 6 20 cores at the junction with the antenna feed. Use this al value and the formuia beiow to calcuiate the number of turns for a specific inductance. G18 55 385 6 6 green red a good dc saturation characteristics.

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

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. Powder core solutions for next gen communications. Micrometals alloy powder cores are becomming increasingly popular for emerging applications in 5g hardware and power systems due to their high efficiency and reliability.
