A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical electromechanical and magnetic devices such as electromagnets transformers electric motors generators inductors magnetic recording heads and magnetic assemblies it is made of ferromagnetic metal such as iron or ferrimagnetic compounds such as ferrites.

Iron powder core transformer.

Normally powder cores are not machined after processing. Iron powder core selection for rf power applications jim cox micrometals inc. The charts that are created by manufactures should show the best type of powered iron to use for specific frequency ranges. Our optimized alloys like oc and od are formulated specifically to deliver exceptional dc bias or core loss performance.

Powdered iron cores are available in e e i u and u i shapes. Saturation can range from to 14 kilogauss depending on type. You can also sometimes find powdered iron in some audio products like an audio inductor in telephones. Powder core solutions for next gen communications.

There are many types of powdered iron materials. Flux is sufficiently small. Flux can be high as long as the a c. The powder cores such as powder molypermalloy and powdered iron materials are die pressed into toroids ee cores and slugs.

The iron powder cores shown in the above tables are primarily used for either high power feed line chokes for common mode current reduction or for 4 1 and 9 1 very high power transmission line transformers. For e cores 100 turns will be used as the standard testing criteria. Powder iron is frequently used as ripple filter inductors in d c. 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.

The purpose of this article is to present new information that will allow the rf design engineer to select the proper iron powder core for inductors and transformers handling power in the 250 khz to 5 mhz frequency range. Examples of the use of powdered iron can be found in rf filters rf amplifiers and if amplifiers. Ltd specialises in the field of magnetics magnetics industry covering a variety of products services in transformers winding machines ferrite cores iron powder cores alloy powder cores bobbins test equipment s dispensing systems. Micrometals alloy powder cores are becomming increasingly popular for emerging applications in 5g hardware and power systems due to their high efficiency and reliability.
