Iron Powder Core

For e cores 100 turns will be used as the standard testing criteria.

Iron powder core. 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. Because it hasn t been conducted in the high temperature so it s used temperature is 65c 125c. 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. Powder core solutions for next gen communications.

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. Iron powder cores general material properties material reference permeability µo temp. Our optimized alloys like oc and od are formulated specifically to deliver exceptional dc bias or core loss performance.

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. Micrometals alloy powder cores are becomming increasingly popular for emerging applications in 5g hardware and power systems due to their high efficiency and reliability. Iron powder toroidal cores for resonant circuits material 0 permeability1 freq. The al value of each iron powder core can be found in the charts on the next several pages.
